Discussion Overview
The discussion revolves around the feasibility of analyzing signals from a 57Co radioactive source using an ADC with a specific sampling rate. Participants explore the technical requirements for pulse height spectrum analysis and coincidence counting between different energy levels emitted by the source.
Discussion Character
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant inquires about the possibility of using a 5 GS/sec ADC to analyze signals from a 57Co source and mentions interest in pulse height spectrum and coincidence counting.
- Another participant notes that the type of detector used is crucial, as the ADC cannot detect pulses directly and questions the meaning of "pulse duration" in this context.
- A participant confirms the use of NaI(Tl) detectors and asks if they can be connected to the ADC, referencing a specific document for pulse shape information.
- It is pointed out that a pulse width of 50 microseconds renders a 20 ns time resolution less beneficial.
- One participant advises that amplifying the signal before connecting it to the ADC is standard practice and necessary for obtaining a clear signal.
- A participant expresses the intention to set up a coincidence instrument using specific energy levels as start and stop signals, and seeks clarification on the use of various electronic components for this purpose.
- There is mention of differing opinions on whether coincidence setups can be effectively achieved with flash ADCs or if conventional NIM modules are required.
Areas of Agreement / Disagreement
Participants express differing views on the suitability of using a flash ADC for coincidence counting and the necessity of conventional NIM modules. The discussion remains unresolved regarding the best approach for setting up the coincidence instrument.
Contextual Notes
Participants reference specific pulse durations and detector properties, indicating that assumptions about pulse shape and timing may vary based on the detector used. There are unresolved questions about the technical setup for coincidence counting.
