High voltage multichannel system

HIGH VOLTAGE MULTICHANNEL SYSTEM

The high voltage multichannel system consists in a chassis which takes high voltage cassettes in 3U format. The voltage / current range is very wide. The standard model (CPS) offers voltages up to 30 kV, the very low noise and reversible polarity model (DPS) works up to 6 kV, and the high power model (EPS) with 60 W. The voltage ranges are from 500 V to 30 kV depending on the model, covering a large number of applications. The multichannel system offers 4 channels, 8 channels and 10 channels.

These high-voltage cassettes are integrated into an high voltage multichannel system ‘half rack’ format (max. 4 HV channels) and in ‘full rack’ format (8 channels or max. 10 HV channels), with a height of 3U. In this case; they are steered by a controller that has a USB and Ethernet port. A high-performancesoftware is available on request, please ask us.

Together with our high voltage switches from CGC Instruments, they are used in applications involving electrostatic quadrupoles, penning traps, paul traps and in general in ion beams.

MICC CONTROLLER AND HIGH VOLTAGE MULTICHANNEL CHASSIS

Modular solution:

The high voltage 3U chassis is available in portable half rack formats carrying 4 cassettes (ECH 124) and in formats for 19” racks, with 8 cassettes (ECH 128) or 10 cassettes (ECH 12A).

Unlike the other high voltage chassis in the Iseg range, the 3U high voltage chassis does not have a digital bus. The information passing through the backplane is analog and a USB and Ethernet controller equipped with 20-bit DAC and 24-bit ADC converters allows communication with the outside world. The resolution is very high with for example 10 mV on a potential of 1000 V.

Automatic identification:

The DC-DC cassettes are now equipped with an identification chip (ID-chip) for automatic detection of the allocated slot. Any crossing of cassettes in slots which are not allocated to them results in an error. In this case, the controller must be configured using a dedicated software procedure (see article ‘MICC controller calibration’) so that it recognizes the location of each cassette. When this is done, the MICC controller identifies only the high voltage blocks during commissioning.

Thanks to its flexibility, the high voltage 3U chassis is suitable for ion beam applications, in particular with ion extraction, supply of lenses by switching polarities, supply of deflectors, supply of Wien filters.
