The CR-150-R5 prototyping test board will aid the experimenter in using and evaluating Cremat's charge sensitive preamplifiers (CSPs). The board has an 8-pin socket for the insertion of the CSP module, as well as power connectors, a power supply regulation circuit and other components needed to filter the detector bias. The CR-150-R5 can be used with any of Cremat's CSP modules: CR-110, CR-111, CR-112, and CR-113. Cremat’s shaping amplifier modules (CR-200 series) are NOT compatible with this board.

Power Requirements:

The CR-150-R5 evaluation board can be powered in either of two methods: The first method is to apply both positive and negative DC power to the CR-150-R5 board. A 3-terminal connector block is supplied for this purpose. The user should provide a supply voltage to the power input of the CR-150 within the range of +/-8 V to +/-15 V.

The second method is to connect a +24V wall-mount power supply to the ‘barrel-style’ power connector on the CR-150-R5 board. Cremat offers a suitable wall-mount power supply for this purpose, which can be used internationally (model CR-24V).

Board dimensions: 3.7 in. x 2.3 in x 0.063 in.

Electrical Shielding:

Cremat's CSPs are sensitive, and operating them in an unshielded environment will usually result in the amplification of unwanted stray signals. For this reason we recommend using the CR-150-R5 board inside a shielded enclosure. We offer the CR-150-BOX-R5 (available separately) which provides shielding for the CR-150-R5

board and is easily assembled and operated.

Voltage Rating

The CR-150 board can be used with detector voltages up to 2000V. BNC connectors, however, are only rated for voltages up to 500V. To use bias voltages higher than 500V, we recommend that SHV-type high voltage coaxial connectors be used instead of the BNC connectors in both the 'bias in' and 'detector' positions.
