CATRiNA
Introduction
The Compound Array for Transfer Reactions in Nuclear Astrophysics (CATRiNA) [1] is a neutron detector array located at Florida State University. CATRiNA is composed of 32 deuterated-benzene () liquid scintillators. The array consists of 16 "small" detectors which has 2" x 2" aluminum cell each and 16 "large" detectors that has a 4" x 2" aluminum cell each. Due to the anisotropic light-output spectrum of of neutron-deuterium scattering, the light-output can be converted to the neutron energy without time-of-flight information in a process known as spectrum unfolding [2]. Please refer [| here] for setting up the HV source for CATRiNA.
Light-Output Response
From previous work, the light-output response of a given CATRiNA detector can be parameterized as a function of incident neutron energy and experimentally-extracted parameters:
The light output parameters are given by the following table [2]
| Size | a | b | c |
|---|---|---|---|
| 2" x 2" | 0.6193 | 2.036 | 0.2592 |
| 4" x 2" | 0.6109 | 1.946 | 0.2625 |
Digitizer setup for coincident with RF
Digitizer 1 is the master, and received the RF-coin signal. Digitizer 2 and 3 are the slaves, connected to the neutron detectors
The TRG-OUT of digi-2 and -3 will be "on" when ever any channel is fired. To do so, the Local Shaped Trigs [G] must be OR.
also, the TRG-OUT Mode is Trigger (Mask) and the TRG-OUT Mask buttons are green for all channels.
Time sync
Digitizer 1 is SW controll and internal clock. The TRG-OUT mode is "RUN".
Digitizer 2 and 3 are S-IN and external clock.
