Hardware

Overview

The HELIOS Digital DAQ is consist of 5 main devices and 1 computing resource.

1. The Digitizers
2. DAQ (the data acquisition computer, located at the HELIOS experimental room, near the Digitizers)
3. Windows ( the windows XP pc for magnet control, Bias control, Target fan control, & Laser range finder)
4. MAC (the iMac that use to do online analysis and remote control of the DAQ)
5. HeliosDB (the Ubuntu pc for database and Grafana, remote to the Windows)
6. LCRC ( the super computer cluster provided by ANL, use for data storage and other computation )

Control and Data Flow

Setup of Array-RF TAC

- can we see NIM signals from triggers out of router or master trigger? -- First likely need trigger map for energy signals, e.g., not Internal mode but (TTL or TTCL modes).

- Able to take various data inputs...RF Stop, TAC, MT A/B outputs (w/ or w/ out cfd post-processing...)

VME

Power supply polarities need to be switched to accommodate additional power of new digitizers!
