= Important Info =

When using an alpha source, it is possible to remove the sample from its container. For certain calibration purposes, such as calibrating the S1 and S2 silicon detectors, it is recommended to remove a sample of the alpha source and attach it to a target ladder.

= Light-Output Response =

From page 570-571 of Radiation Detection and Measurement by Knoll, the recoil neutron energy is given as a function of the target recoil angle in the lab frame <math> \theta </math>, incident neutron energy <math> E_n </math>, and nucleon number of target nucleus <math> A </math>

<math> E_{recoil} = \frac{4A}{(1+A)^2}cos^2\theta E_n </math>

For maximum energy transfer, <math> \theta = 0 </math>, and

<math> E_{recoil} = \frac{4A}{(1+A)^2} E_n </math>

For deuterium, <math> A = 2 </math> which implies a maximum deposited neutron energy of <math> E_{recoil}/E_n = \frac{8}{9} </math>.

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:

<math> LO = aE_{dep}-b(1-e^{-cE_{dep}}) </math>

The light output parameters are given by the following table <ref name="Morelock2022">A. B. Morelock et al. NIMA '''1034''', 166759 (2022) https://doi.org/10.1016/j.nima.2022.166759 </ref>

Ptolmey GUI

2026-03-16T00:44:15Z

Mgm2001:

[[File:Ptolemy GUI.png|thumb|500 px| right|Screenshot of Ptolmey GUI]]

The Code [https://fsunuc.physics.fsu.edu/git/rtang/PtolemyGUI Download here] is a wrapper for DWBA calculation using [https://www.phy.anl.gov/theory/ptolemy/ Ptolemy], developed by M. H.. Macfarlane and Steven C. Piper. The wrapper simplifies the input by using global potentials. An input for a reaction reduced to a single line as

#reaction gs-spin orbital spin-pi(Ex) Ex ELab Potentials
11C(d,p)12C 3/2- 0p1/2 2+ 4.4 10MeV/u AK

= Interface =

There are two interfaces available, one is using CERN ROOT with Qt4 (which is legacy), another is based on python Qt6 (preferred).

== CERN ROOT Qt4 ==

This developed like on 2018 together with the HELIOS analysis packages, the code is written by C/C++. There are 5 elements

# InFileCreator.h -- for creating the inFile used by Ptolemy
## Isotope.h -- for reading the mass table
## potential.h -- for the global optical potentials
# ExtractXSec.h -- for extracting the Xsec distribution, saved it into txt file and root file.
# PlotTGraphTObject.h -- for plotting the distributions stored in the root file

== Python Qt6 ==

This is recently developed on 2024, Nov. This code only use the Isotopes.h, potential.h and inFileCreator.h. The Xsec extraction and plotting are pure python.

In addition, it can ask IAEA for excitation and plot the Ex levels.

= MAC OS support =

Python Iseg HV controller

2025-05-01T03:17:08Z

Mgm2001:

The Iseg HV modules are using Mpod crate. A Mpod-C (controller) is used to control the HV module.

The Mpod-C can be controlled via ethernet, USB, or CAN. For the ethernet, it requires an IP.

= GUI control and monitor =

[[File:IsegHVContol Screenshot.png|thumb]]

https://fsunuc.physics.fsu.edu/git/rtang/IsegSNMPGUI

The GUI also push monitor values to database and display on Grafana https://fsunuc.physics.fsu.edu/grafana/d/JG7ADC67z/iseg-hv-monitor?orgId=1&refresh=5s

= Iseg HV with Wiener Mpod =

to control the Mpod-C via USB (say, setting up the IP), in Windows, install the MUSEController.

== IP address ==

ANASEN : 208

Catrina : 128.186.111.101

== SNMP ==
More detail can be found in [[:File:Iseg SNMP Programmers Guide.pdf | here]].

In linux, install snmp

sudo apt install snmp snmp-mibs-downloader

copy the [[:File:WIENER-CRATE-MIB.txt|WIENER-CRATE-MIB.txt]] into /usr/share/snmp/mibs/

=== Python GUI for control and monitor ===

https://fsunuc.physics.fsu.edu/git/rtang/IsegSNMPGUI

This program should be suitable for all Iseg HV modules using Mpod-C with SNMP protocal.

The only hard-coded thing is the Mpod-C IP, and the database IP and name.
