Timelines for the test place in Moscow 2013 2014 Q1 Q2 Q3 Q4 Purchase of the equipment and manufacture details of target Assembling of the target Vacuum test Cold test Preparation stage for target in Moscow 2013- Q1 2014 is finished: test place, frame for target, water, light, power supply, pumping out lines, drawings, purchase of equipment, production of details, 3 PC for data taking and operation. Assembling stage and vacuum tests Q4 2013 - Q2 2014 are going on.

Assembling stage for target Q4 2013- Q2 2014 Already done: Assembling of cryostat, installation of cryo-cooler, assembling full vacuum pumping system, temperature and pressure sensors are installed, leakage tests for cryostat and vacuum system (10-7 mbar), commissioning of cryo-cooler. Recently done: Gas supply system is assembled and tested for leakages. New type of condenser is produced, assembled and tested for leakages New generator New skimmer Going on: Assembling of the internal parts. The regular low temperature tests (without cooled gas) after installation of each internal part. Minimization of radiation heating. Maximization of transfer of the cooling power. Installation of the new adjustment system. Installation of the gas supply lines inside the cryostat.

Assembling stage for target Q4 2013- Q2 2014 Gas supply system

Assembling stage for target Q4 2013- Q2 2014 Installation of new adjustment system Upper part of the system New type of the condenser Lower part of the system
