Overview

This family of High Voltage power supplies includes single and double width boards housing up to 48 output channels. The boards are designed to provide voltage up to 3.5 kV, and current up to 3.5 mA. 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). Common Floating Return allows on-detector grounding reducing the noise level; the floating return is insulated from the crate earth up to ±25 V.

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 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.

A7030

A7030 is the line of power supply that offers you all the safety, performance and control of a completely independent channel technology at the cost effective price of a distributor!
You will never have to compromise! Well suited for large PMT arrays, housing 48, 36, 24 or 12 independent high voltage channels available with either positive or negative polarity. The output voltage range is 0 ÷ 3 kV, with 5 mV monitor resolution. The maximum output current is 1 mA (1.5 W max. output power), with 2 nA monitor resolution. The A7030 is supplied in different versions equipped with SHV or with Radiall multipin connector. Two A7030 versions are designed for higher altitudes (operating altitude: up to 5000 m):
– A7030Y – 48 channel Radiall multipin connector
– A7030YS – 24 channel SHV connectors

A7236 / AG7236 / A7435 / AG7435

A7236 and A7435 are the new pair of CAEN general purpose power supplies that will provide you with tremendous power and resolution performance at a cost effective price! You will never have to compromise again. The x7435 and x7236 house 12, 24 or 32 independent high voltage channels, available with either positive or negative polarity. The boards are available in different versions equipped with SHV or Radiall Multipin connectors. The output voltage range is 0 ÷ 3.5 kV, with 5 mV of set and monitor resolution. The output channels offer dual current ranges (software selectable): 

• A7236/AG7236 Dual range current
– High Power: 0 ÷ 1.5 mA; Iset/Imon resolution: 10/5 nA  (4 W max.)
– High Resolution: 0 ÷ 150 µA (Iset/Imon resolution: 10/500 pA)

• A7435/AG7435 Dual range current
– High Power:  0 ÷ 3.5 mA; Iset/Imon resolution: 10 nA (9 W max.)
– High Resolution: 0 ÷ 350 µA; Iset/Imon resolution: 10/1 nA

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.

Software

A complete set of Software Tools is available (free download) to control CAEN Universal Multichannel Power Supply Systems, from low level libraries to graphical application software:

CAEN, in collaboration with CERN, has developed an OPC server which allows control of its power supply systems by any OPC compliant client application.
HiVoCS HiVoCS is a Web Interface available on any SY4527-SY5527 CPU. This Interface can be accessed directly via browser without installing any additional software.
EPICS IOC Mainframes CPUs integrates an EPICS Input / Output Controller (IOC) that provides access to the Process Variables using the Channel Access Protocol.
CAEN HV Wrapper Library It is a set of ANSI C functions bundled in a library, providing the software developer an unified software interface for the control of all the CAEN Power Supply products
GECO2020 CAEN General Control SW for High Voltage Boards and Systems. it can manage and control CAEN HV power supplies in any form factor as if they were an unique device.
