ROSMAP (Spectroscopy)

Spectroscopic readout of multi anode PMTs
 
 ROSMAP with PMT attached.

The ROSMAP is a compact system for readout of multi-anode photo multiplier tubes (PMT). The system is designed to interface with the Hamamatsu H8500C multi-anode PMT. The system has a configurable serial interface for data acquisition.

In the spectroscopy version of ROSMAP, the energy values are available for readout as 8 bit digitized values over the data interface. The 8 bits correspond to the full range of 0 to -200pC at the input of the module. The module can buffer a number of events locally before readout.

Each anode is connected to its own charge sensitive amplifier located on an application specific integrated circuit (ASIC) from IDEAS.

The module has internal triggering, generated from the PMT dynode signal (DY12). The trigger level can be adjusted to fit the application, by the programming internal system registers. The system also includes an internal calibration circuit.

The readout system amplifies and digitizes the signals from the sensor. The serialized digital data is provided over a standard serial interface. The output data interface can be connected to a PC or an industrial system. The data interface can be customized to the user’s needs.

The system includes internal power regulation and conditioning.

The system is delivered with an executable test system, with functionality to perform basic measurements with an attached PMT. Source code for the test system can be delivered by agreement.
