March. (Petitjean, Vasilyev, Vznuzdaev, Ivanov)
1. Assembling of new support system.
2. Installation of new elements of high voltage system.
3. Vacuum and cryo- tests with the new HV-elements.
4. Installation of new grid and Macor pad plane into Cryo_TPC.
5. Installation of new Capton flat cables.
6. Repairing of CUPS.
7. Assembling of cryogenic Impurities Concentration System (ICS) - absolutely new element.
8. Tests in Zurich isotopic purity of deuterium from Hydrytes (our prepared deuterium).


April. (Petitjean, Vasilyev, Vznuzdaev, Ivanov, Kravtsov, Ganzha, Petrov, Martyushov)
1. Common tests of the system. (Cryo-, vacuum, slow control)
2. Suppression of the noise from cold head. Suppression of the mechanical resonances at cryogenic temperatures.
3. Optimization of resolution on base of signals from alfa-source.
4. Calibration of the temperature sensors in Cryo_TPS on base of liquid deuterium vapor pressure.
5. Connecting of Cryo_TPC to circulation system (CHUPS) and ICS. Purification.
6. Approbation of the ICS principles on 1 ppb level of impurities.
May. Beam time.

We propose to use during Spring usual deuterium (not isotopic purified). Reason is very simple. If we will lose during Spring work deuterium we will not be able to produce new for the Fall beam time.
In Spring we mainly can test all our systems. For it standard deuterium is sufficient (?).
