is an experiment to determine the composition of <a href="/wiki/Cosmic_ray" title="Cosmic ray">cosmic rays</a> up to the 10<sup>15</sup> eV (also known as the "knee prospect") in the <a href="/wiki/Cosmic_ray" title="Cosmic ray">cosmic ray</a> spectrum. </p><p>It has been hypothesized that the knee prospect of the cosmic ray spectrum can be explained by the theoretical maximum energy

The measurements are accomplished using a timing-based charge detector and transition radiation detector sent to an altitude of at least 34 km (21 mi) with aid of a <a href="/wiki/High-altitude_balloon" title="High-altitude balloon">high-altitude balloon</a>. </p><p>After launching from <a href="/wiki/McMurdo_Station" title="McMurdo Station">McMurdo Station</a> in Antarctica, the balloon will stay aloft for 60–100 days gathering data on charges and energies of the unimpeded cosmic rays that strike the detectors. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Expected_outcomes">Expected outcomes</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cosmic_Ray_Energetics_and_Mass_Experiment&action=edit&section=1" title="Edit section: Expected outcomes"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>One of the advantages of this type of experiment is that it is possible to identify the original particle that would have caused the <a href="/wiki/Air_shower_(physics)" title="Air shower (physics)">air shower</a> detected by ground-based detectors. Maximum detectable energy level is determined by duration of the flight and size of the detector; a difficult barrier to get around for experiments of this type. An accurate measurement of the composition of cosmic rays is necessary in order to understand the origins of the cosmic rays found above the "knee" at 10<sup>15</sup> eV. To date, the CREAM balloon experiments have accumulated a total of 161 days of exposure, longer than any other single balloon-borne experiment.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:CREAM_3.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/e/e0/CREAM_3.jpg/220px-CREAM_3.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/e/e0/CREAM_3.jpg/330px-CREAM_3.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/e/e0/CREAM_3.jpg/440px-CREAM_3.jpg 2x" data-file-width="640" data-file-height="480" /></a><figcaption>CREAM III takes flight in Antarctica</figcaption></figure> <div class="mw-heading mw-heading2"><h2 id="Experimental_goals">Experimental goals</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cosmic_Ray_Energetics_and_Mass_Experiment&action=edit&section=2" title="Edit section: Experimental goals"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li>Can the "knee" be explained by maximum acceleration due to supernovae?</li> <li>Have the composition of cosmic rays changed over time?</li> <li>Are multiple mechanisms responsible for the production of cosmic rays?</li></ul> <div class="mw-heading mw-heading2"><h2 id="Construction">Construction</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cosmic_Ray_Energetics_and_Mass_Experiment&action=edit&section=3" title="Edit section: Construction"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Cream2.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/e/e2/Cream2.jpg/220px-Cream2.jpg" decoding="async" width="220" height="205" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/e/e2/Cream2.jpg/330px-Cream2.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/e/e2/Cream2.jpg/440px-Cream2.jpg 2x" data-file-width="1368" data-file-height="1272" /></a><figcaption>Instrumentation of CREAM II.</figcaption></figure> <p>In order to answer these questions, it is of particular interest to investigate cosmic rays in the 10<sup>12</sup> to 10<sup>15</sup> eV region due to several theories predicting a change in elemental composition just below the knee. To determine the elemental spectrum of cosmic rays, CREAM uses a <a href="/wiki/Semiconductor_detector" title="Semiconductor detector">silicon charge detector</a>, <a href="/wiki/Time-of-flight_mass_spectrometry" title="Time-of-flight mass spectrometry">timing charge detector</a>, and scintillating fiber <a href="/wiki/Hodoscope" title="Hodoscope">hodoscopes</a> to detect the charge of incident particles up to that of iron (Z = 26). Energies are measured with a <a href="/wiki/Transition_radiation_detector" title="Transition radiation detector">transition radiation detector</a> (TRD), along with an ionization <a href="/wiki/Calorimeter" title="Calorimeter">calorimeter</a>. Because all detectors are in close proximity of each other, it is a prime concern to minimize the interaction between showers produced in the calorimeter, and the charge-measuring instruments. To dampen this effect, CREAM uses a larger number of pixels with a smaller area, along with a very fast readout time to differentiate between events caused by the primary particle and events caused by back-scattering from the calorimeter. </p><p>The relatively low density of the TRD allows for a larger detector geometry to detect particles with a lower flux. By measuring the <a href="/wiki/Lorentz_factor" title="Lorentz factor">Lorentz factor</a> <i>γ</i>, combined with knowledge of the particle's charge, it is possible to calibrate the detector with various cosmic rays of charge ±1 (electrons, pions, muons, etc.). Because of the relatively low geomagnetic cutoff energy for cosmic rays near the South Pole, a <a href="/wiki/Cherenkov_detector" title="Cherenkov detector">cherenkov detector</a> is placed between modules of the TRD to act as a veto for these low-energy particles.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p><p>For power, the system includes batteries for energy storage, along with a solar array rated to sustain the mission for 100 days. Altogether, the instrument is expected to draw only 380 watts from a 28-volt supply, thanks to a very careful choice of energy-efficient electronics. In near-vacuum conditions, significant precautions must be taken against coronal discharges between unshielded electronics operating at as low as 100 volts. This is mitigated by encasing all relevant electronics in a lightweight dielectric compound, such as plaster. </p><p>The instrument must be able to operate in a wide range of temperatures, as the high albedo of Antarctica can cause very high temperatures, while periods of darkness will result in very low temperatures. </p><p>Excluding the ballast, total weight of the instrument must not exceed 5,500 pounds (2,500 kg) to reach the desired altitude. Retrieval is done by separating the instrument from the balloon after a sufficient amount of exposure, and a parachute opens to somewhat slow the descent of the instrument. Although the experiment is designed to meet the structural requirements of the <a href="/wiki/Columbia_Scientific_Balloon_Facility" title="Columbia Scientific Balloon Facility">Columbia Scientific Balloon Facility</a>, it is inevitable that some damage will be incurred to replaceable parts of the instrument. The main priority is data retrieval; all other systems are considered secondary at this point. </p> <div class="mw-heading mw-heading2"><h2 id="CREAM_Flights">CREAM Flights</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cosmic_Ray_Energetics_and_Mass_Experiment&action=edit&section=4" title="Edit section: CREAM Flights"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <table class="wikitable" style="margin: 1em auto 1em auto; text-align:left;"> <caption>CREAM Flights (Launch history) </caption> <tbody><tr style="text-align:center; background:#BBB;"> <td><b>Year</b> </td> <td><b>Start Date (UTC)</b> </td> <td><b>End Date (UTC)</b> </td> <td><b>Flight</b> </td> <td><b>Reference</b> </td></tr> <tr> <td>2004 </td> <td style="text-align:right; nowrap;">December 16, 2004 </td> <td style="text-align:right; nowrap;">January 27, 2005 </td> <td>CREAM I </td> <td><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </td></tr> <tr> <td>2005 </td> <td style="text-align:right; nowrap;">December 15, 2005 </td> <td style="text-align:right; nowrap;">January 13, 2006 </td> <td>CREAM II </td> <td><sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </td></tr> <tr> <td>2007 </td> <td style="text-align:right; nowrap;">December 18, 2007 </td> <td style="text-align:right; nowrap;">January 17, 2008 </td> <td>CREAM III </td> <td><sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </td></tr> <tr> <td>2008 </td> <td style="text-align:right; nowrap;">December 18, 2008 </td> <td style="text-align:right; nowrap;">January 7, 2009 </td> <td>CREAM IV </td> <td><sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </td></tr> <tr> <td>2009 </td> <td style="text-align:right; nowrap;">December 1, 2009 </td> <td style="text-align:right; nowrap;">January 8, 2010 </td> <td>CREAM V </td> <td><sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> </td></tr> <tr> <td>2010 </td> <td style="text-align:right; nowrap;">December 21, 2010 </td> <td style="text-align:right; nowrap;">December 26, 2010 </td> <td>CREAM VI </td> <td><sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> </td></tr> <tr> <td>2016 </td> <td style="text-align:right; nowrap;">November 28, 2016 </td> <td> </td> <td>BACCUS </td> <td><sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> </td></tr> <tr> <td>2017 </td> <td style="“text-align:right;">August 13, 2017 </td> <td style="“text-align:right;">February 2019 </td> <td>ISS-CREAM </td> <td><sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> </td></tr></tbody></table> <div class="mw-heading mw-heading3"><h3 id="ISS-CREAM">ISS-CREAM</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cosmic_Ray_Energetics_and_Mass_Experiment&action=edit&section=5" title="Edit section: ISS-CREAM"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Pronounced "ice-cream", ISS-CREAM is the next generation version of the CREAM balloon experiments that was sent to the <a href="/wiki/International_Space_Station" title="International Space Station">International Space Station</a> on August 14, 2017, with the <a href="/wiki/CRS-12" class="mw-redirect" title="CRS-12">CRS-12</a> mission, and will be installed permanently to the station.
