3. Introduction

The PA1 Power Amplifier is the power amplifier for the HCS1 Helmholtz Coil Control System. The
full HCS system consists of:
• HC1 or HC2 Helmholtz Coils: an assembly of up to three Helmholtz coils. See OM3226 (HC1)
or OM3342 (HC2).
• PA1 Power Amplifier.
• CU1 Control Unit: the control unit for the system which enables it to interface with a PC-
based test, measurement and control system. See OM3224.
A diagram showing the connection of these separate items into one system is given in
A.
The PA1 Power Amplifier is available in a number of variants to match the coil assembly it is
being used with:
• PA1-1X, PA-1Y, and PA1-1Z Single Axis versions
• PA1-2XY, PA1-2YZ, and PA1-2XZ Two Axes versions
• PA1-3 Three Axes version
