AMS-02 FOR THE FIRST TIME AT -90 C

April 7th, 2010

Yesterday, on the 6th of April, the shroud of the Large Space Simulator reached -90 C, simulating cold environmental conditions. In these conditions, even if the electronics of the experiment is switched on, dissipating overall 2,5 kW of power, there is the need to activate heaters located in various part of the experiment to avoid that some subsystems reach temperatures lower than the minimal operating temperature and get damaged. During the entire period of the test, a team of 20

PREPARING FOR THE TVT (Thermo Vacuum Test)

April 5th, 2010

The preparation of this test has taken more than three weeks.  ESTEC test center hosts the largest space simulator in  Europe, one of the largest in the world. In order to perform this test, the AMS-02 experiment needs to be installed on a special stand, dubbed “gondola”, built with amagnetic steel to be insensitive to the AMS-02 magnetic field, in order to be rotated in an horizontal position. The AMS-02 payload has been equipped with hundreds of temperature sensors, to

A LONG LIFE FOR THE ISS AND AMS-02

March 12th, 2010

At the recent meeting in Tokyo of the Heads of Agency supporting the International Space Station Joint Statement an important decision about the extension of the ISS exploitation has been taken. Exploitation of the ISS will be extended from 2015 to 2020 at least, and possibly to 2028. Since AMS-02 will not return to Earth after its installation on the ISS on 2010, the decision to extend the duration of ISS operations will have a potentially significant impact on the

READY FOR EMC (Electro Magnetic Compatibility) TESTS

February 28th, 2010

After little more than a week of preparation the AMS-02 spectrometer has been installed in the EMC test chamber at ESTEC. The walls of this test chamber are completely covered by piramids of a radiation absorbing material (the bluish color in the photo), which ensure that the radiation hitting the wall is not reflected back (echo) making it hard to interpret the results. This configuration makes the test chamber  anechoic,  that is “without echo”.  A series of tests were performed
