a) Vadim requested material budget in terms of radiation length for the new
target system in 0 and 180 mrad scattering angles.

b) Dilution cryostat was closed with test vacuum flange and tube without the 
glass fiber mixing chamber. The microwave feed throughs were closed with blind
flanges. No leaks from 3He or 4He circuits to isolation vacuum were observed 
and no leaks in the outer vacuum case from outside. Also target holder 
and precooling plug vacuum were leak tested. 

c) Target cells from run 2004 were removed from the target holder Kevlar tube.
Inserting of the shorter target holder for new magnet was tested in the clean
area. The two target cell system for conical cavity with deuteron NMR coils 
is ready if it is needed in the technical run before physics data taking.

d) Alain: 2.5 T field map of the magnet was done and interaction with SM1 was 
tested. Solenoid moves 1.5 mm up or down at downstream end depending on the 
sign of the current. At upstream end the movement is 0.5 mm up or down.

e) Davide was preparing LH2 target. To be tested in September/October.

f) Offer for new AVS47A resistance bridge for thermometers EUR 4125 with 
IEEE-488 Computer Interface EUR 1250.
