Inquiry (采购产品): HV cables This is just a quick inquiry to see if you can make custom high-voltage cables (up to 5 kV) that are Helium-proof to connect to an avalanche photo-diode.

The problem with our current cables is the He penetrates the cable & causes sparking. **** Hidden Message ***** Chris Milne 5222 Umiken, Sw Company: PSI E-mail: chris.milne@psi.ch **** Hidden Message ***** chris.milne@psi.ch
