Steps of cryostat assembly and cleaning with new systems
I.   Separation of tank from head and head disassembly
II.   Tank baking in oven at 95 °C
III.   Head cleaning
  1. Pre-cleaning by hand by hand with acetone
  2. First ultrasonic bath in Tickopur detergent
  3. Second ultrasonic bath in pure water or non-ultrasonic bath
  4. Baking of parts ( metal 180 °C, epoxy 130 °C, boards 85 °C, CCDs 60 °C )
  5. Dust removal
IV.   Tank pumping ( sorption pump 130 °C, mass spectrum analysis )
V.   Integration and assembly of head with pre-adjustment
VI.   Inside cryostat wiring
VII.   Gluing of sensors and cleaning of residuals
VIII.   Testing of wiring
IX.   CCD alignment
X.   Integration of head with tank - leak test
XI.   Pumping ( may be with heating from outside )
XII.   Cryostat ready
