Circuit arrangement for acquiring signals from a device for measuring charged particle beams for external radiotherapy<\/h1>\n

How does it work?<\/span><\/h3>\n

[\/vc_column_text][vc_empty_space][vc_column_text]The technological configuration comprises a sensor equipped with ionization chambers, which in turn consists of a plurality of sensor channels. The circuit layout is formed by a series of channel branches arranged in parallel, set up to be connected to the respective sensor channels in order to receive input signals. Each channel branch includes a current-frequency converter and a counter, which provides a count value representative of the charge detected by a given channel. The signals thus processed can be routed to a single parallel output via a multiplexer. <\/p>\n

The circuit layout described can operate with ionization chamber sensors whose channels are arranged in a stack that develops along the beam direction, but they can also operate with two-dimensional sensors, known as pixel ionization chamber detectors.[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n
