GENERAL
Description
The Model
VME4877 is a triple-width VME module used to supply HIGH DC voltage to
detectors in a modular, upgradable, computer
controlled environment. This 8 channel module with its interchangeable pods has
12-bit setting resolution and extremely low voltage ripples. Computer control
has allowed many special features to be developed for the supply, including
user-defined control and monitor groups, variable ramp rates, and advanced
histogram and graphic features. This 6U unit can be used independently or in a
large system. In both cases, a special J2 backplane is required. The system is
designed to the VME-bus standard with up to 48 supplies per standard VME crate.
The 12-bit
setting resolution is stable with acceptable voltage levels of less than 100 mV
rms for frequencies less than 1 kHz and less than 10
mV rms at higher frequencies. Computer controlled
monitoring is achieved via 15-bit ADCs resulting in least count sensitivity of
(full scale/32,768) for voltage and current on all pods.
The HV supplies
were designed to be as simple as possible with complete computer control and
monitoring that incorporates many special features. For example, a common ramp
rate can be defined in a group and a maximum difference voltage between any two
supplies in the group can be set. The computer monitors the voltage and current
of the supply (keeping a running time history of current drawn) as well as the
temperature of the module and the values of the low voltage supply voltages.
Variable ramp rates and user defined supply groups are other software features.
PC software is available which uses a popular commercial PC/VME interface.
* The 5.5kV Power Supplies are limited to 6 watts within a
voltage-current limit envelope.
