This family of High Voltage power supplies includes single and double width boards housing up to 24 output channels. The boards are designed to provide voltage up to 8 kV, and current up to 1 mA with up to 100 mV set and 10 mV monitor resolution. All the boards are compatible with all CAEN Universal Multichannel Power Supply Systems. The available grounding option, depending on the family are the following: Common Ground (AGxxxx) or Common Floating Ground (Axxxx) except for the A1534 that features individual foating channels insulated up to 100V. Common Floating Return allows on-detector grounding reducing the noise level; the foating return is insulated from the crate earth up to ±50 V (with a 65 V hardware limit).
The HV ramp-up and ramp-down rates may be selected, for each channel, in the 1 ÷ 500 V/s range (1 V/s step). The boards are provided with both current and voltage protections. If overcurrent occurs, the relevant channel can be programmed either to turn of after a programmable trip time or to remain on and to provide the maximum allowed current. This particular feature allows the module to perform as a current generator. Channels may be enabled or disabled via the Interlock logic. The voltage ramp rates may be set independently for each channel.
A1550 / AG550
A1550 / AG550 houses 12 or 24 independent high voltage channels and is available in different versions equipped with SHV or with Radiall Multipin connector.
The output voltage range is 0 ÷ 5 kV, with 500 mV set and monitor resolution. The maximum output current is 1 mA , with 100 nA current set and monitor resolution. The board is available with either positive or negative output polarity.
A1560H / A1580H
A15x0H boards are specifically designed for Germanium detector. They house 8 or 16 independent channels equipped with an individual enable and with SHV or Radiall Multipin connector. Positive, negative or mixed polarities are available. The output voltage range is 0 ÷ 6 kV (A1560H) or 0 ÷ 8 kV (A1580H), with 10 mV monitor resolution. The maximum output current is 20 µA, with 50 pA monitor resolution. The HV ramp-up and ramp-down rates may be selected, for each channel, in the 1 ÷ 500 V/s range (1 V/s step).
A1534 is a single width board housing 6 High Voltage floating channels equipped with CPE connectors. The channels feature independent returns, insulated up to 100 V between each other. The board is available with positive or negative polarity and is non-reversible. The output voltage range is 0 ÷ 8 kV (200 µA maximum output current) with 0.5 V monitor resolution.
A7460 houses 12 independent high voltage channels with dual current full scale range and is available with positive, negative or mixed polarity.
The output voltage range is 0 ÷ 6 kV with 10 mV set/monitor resolution. The maximum output current is 1 mA with a 5nA setting resolution. The monitor resolution is 5 nA in the high range (1 mA) and 500 pA in the low range (100 µA).
Universal Multichannel System - Mainframes
Modularity, Compatibility, Connectivity, Usability and Solidity are the keywords of the system design. The Mainframes have been specifically designed to power all detector technologies found in modern Physics Experiments, such as photomultipliers, wire chambers, streamers tubes, silicon detectors and others.
The systems are modular, flexible and match not only the requirements of major experiments with large number of channels but also the practical needs of test laboratories, where simple manual operations on a limited number of channels are often desired.
