a) The safety valves were unmounted on Wednesday and sent to Safety Commission 
for inspection. The magnet safety valve was installed back on same day.

b) The carbon filter after the 4He rotary pump was opened. On small sample of 
the carbon pellets it is difficult to see oil on the surface. The oil on
bottom may come from spilling when the pumps are initially started and they 
work with maximum power. When the zeolite filter material was replaced with
the carbon it looked also dry.

c) Eight new 0 - 15 A trim coil power supplies were ordered.

d) Offer for new Teledyne Hastings flow meter power supply ENALL-P Digital
Panel is CHF 2500.

e) Andrea compared different target cell diameters in talks given in technical
board and analysis meetings. The technical board discussed on this. One 
possibility would be to produce 40 mm diameter target cells for the proton
runs in 2007 - 2008. Jaakko produced preliminary drawings for the 40 mm
target cells:
