GEM supply, assembly and test
 We received:
• 7 standard + 10 Au plated GEMs
• 18 frames
 Assembly and test of GEMs is proceeding at an average
of 2 foils per day.
 Shall be able to send to SB within a week a box
containing 11 grids and 13 GEMs
 Rui is producing 20 standard + 10 Au plated GEMS.
Half of them should be send to us by middle of next
week, the rest by the end of the month.
