Fw: UHV feedthrough-connectors

["Semenchuk" <semench@pnpi.spb.ru>]

 Dear Bernhard,

Thanks for your information about support from Berkeley for
feedthrough-connectors payment.
As I remember for two new flanges we should have 2+3 D50 connectors and 2
connectors on 12 kV (2-conductor).
Concerning spare connectors I can say that it is need at list
1 D50 and 1 on 12 kV.
 It meens that full number will be 6 D50 and 3 on 12 kV.
But I would like to dicuss this question with our people soon.
Best regards           Gennadi Semenchuk
