Digital twin for accelerators

This twin is based on epics and thor scsi lib. It is provided as an Input Output Controller (IOC). The machine is modelled using thor scsi lib. It's engineering to physics space is implemented by epics records. PyDevice based records are used to get data from the records into thor-scsi-lib.

Requirements

• thor scsi lib: with its further requirements see https://github.com/jbengtsson/thor-scsi-lib for details

  The thor scsi python module has to be available / installed for the interpreter used for Pydevice (see next point)

• PyDevice: https://github.com/klemenv/PyDevice

• Epics: https://github.com/epics-base/epics-base

• For extracting data from the database

  • pymongo
  • pandas
  • numpy
  • bact-math-utils https://github.com/hz-b/bact-math-utils

Building the twin

1. clone the repository from HZB's gitlab e.g:

   git clone https://gitlab.helmholtz-berlin.de/acc-tools/dt4cc.git dt4acc
   

2. build the IOC

   a. from the root directory of this repository change into directory vaccelApp/Db/

   b. extract database data using

   python3 magnet_info_from_db.py

   Please note: you need to have access to pymongo.bessy.de

   c. change into the repositories root directory and start building the IOC using

   make

   d. change into the directory iocBoot/iocvaccel/ and start the IOC with the script

   sh st.sh
