Leak rate

New Gas system from Rainer:– ~0 intrinsic leak rate

Leak Rate < 0.1 mbar* l/h (~precision limit)

with greased gas connectors

See how it develops with realistic configuration: 5 chambers in a row, some angular deviation...

Winding machine

• New winding frame is sturdy enough, even in weight reduced version

• Meteor displays a loss of tension over first windings.

• Winding machine modification: scheduled beginning of Sept. need to check

Material Status

Arrived:• Wacosit profile (frame) arrived:Side profiles warped, but OK after

glueing to Al profiles• Voltage divider PCBs arrived• Signal cables arrivedIn Approach:In Approach:• Padplanes (slight delay, due to

manufacturing confusion): finished end of next week

• Fischer panel:~4 weeks from now

To order:

• Vacuum tables

• Glueing tables

• Connectors (ROB):Minimum 15k pc. = 3930 €

60% TRD: 39k pc. = 10218 €

Need add. Offers? Delay...

Padplane

• Production steps were discussed with Optiprint to optimize mechanical precision where we need it.

• Result: Question from Optiprint 2 weeks ago: „do we need this precision?? Will bring up the price considerably.“

= some unfortunate mixup...

2 week delay
