Chapter 7
MCP-100 Option
This chapter covers the MCP-100 option, an additional HV power supply that can be
installed in the PG-200. This option is required for all lens-coupled intensified detectors,
as well as some specialized models such as ITE/CCD detectors. If you have not
purchased the MCP-100 option, you can skip this chapter.
Dangers and Warnings
Voltages on the MCP-100 option board may exceed 10,000 volts. To avoid possible
hazard to personnel, use the instrument only with the proper connectors and cables and
only for the purposes for which it is designed, i.e. the operation of image intensifier tubes
which are contained in proper housings and equipped with compatible connectors.
Adequate precautions must be taken to prevent persons from making contact with the
output of the MCP-100.
Never plug the AC cord of the pulser into an outlet which is not properly grounded.
Never attempt to operate the unit without covers in place.
Never operate the unit with the high voltage cable disconnected. The high voltage
connectors are designed to seal out air to avoid arcing. An open high voltage connector is
a danger to personnel and can cause damage to the equipment. Connections should be
made before power is turned on.
Before disconnecting any cables, turn the power off and wait at least 5 minutes for
voltages to decay to safe levels.
Always use an outlet which has a properly connected protective ground. Never make
connections to other instruments which might have voltages on BNC shields.
Disconnecting the protective earth terminal, inside or outside the chassis, or tampering
with its operation may render the MCP-100 dangerous and is prohibited.
The high voltage Gate In BNC is located next to the Shutter In BNC on the rear panel.
The Shutter In BNC is the input for a logic level (5 V) signal and should not be
connected to a high voltage gate pulse or damage may occur. Caution should be
exercised not to confuse the two rear panel inputs.
Introduction and Specifications
The MCP-100 option supplies high voltage DC bias for PI image intensifiers plus
circuitry to facilitate gating. The MCP-100 option is mounted inside the PG-200 gate
pulse generator at the factory.
