Laser Control System Workshop

Friday 21 Sept 2018, 14:00 → 17:00 Europe/Zurich

13/2-005 (CERN)

Thomas Elias Cocolios (KU Leuven - IKS)

Small workshop to exchange on the issues faced by the laser ion source and laser spectroscopy communities in an effort to federate our effort and benefit from each other's experience.

14:15 → 15:00 Wavelength measurement and control

Monitoring and scanning the wavelength is mostly done by relying on wavemeters, but there are some pitfalls. Let's discuss some!

14:15 High-resolution wavemeter calibration at Mainz

High-resolution study of a high-precision wavemeter has been done in Mainz. The reproducibility of the calibration is a striking feature.

Speaker: Wilfried Noertershaeuser (University Mainz)

14:25 Laser frequency determination and stabilisation at IGISOL

Speaker: Sarina Geldhof (University of Jyvaskyla (FI))

14:35 Problems and solutions for accurate laser control at Helios and RILIS

The frequency spectrum of the dye laser amplifier in the Helios laboratory in IKS, KU Leuven, has been observed to contain sidebands of the main laser frequency. Multiple orders of these sidebands have are seen and have an offset of about 800 MHz from one another. The origin of this problem and some solutions have been investigated.
Once the output of the laser light is a pure single mode, remote and hands-off operation of the laser system will proof to be very useful. Therefore, an accurate and absolute control of the laser selective elements will be necessary. Tests have been performed at RILIS, CERN, using etalon mounts with absolute positioning.

Speaker: Mr Kristof Dockx (KU Leuven (BE))

15:00 → 15:45 Laser Control System

How laser systems are controlled and integrated, and where we can benefit from existing developments

15:00 Trap CS

The Penning Trap community pooled their resources together and created a Trap CS with frequent updates and full support in Europe and North America.
Its concept and current status will be introduced as an example of what a laser control system could, as well as how it was attempted to apply this CS to some laser spectroscopy experiment (TRIGA).

Speaker: Dennis Neidherr (GSI - Helmholtzzentrum fur Schwerionenforschung GmbH (DE))

15:10 EPICS: an integrated control system

At the accelerator laboratory in Jyväskylä, both the Penning Trap and Collinear Laser Spectroscopy systems are globally integrated into the facility's control system, EPICS. It will be briefly presented.

Speaker: Mikael Reponen (University of Jyväskylä)

15:20 CRISTAL: a distributed control and acquisition system

At the CRIS experiment at ISOLDE, a Python-based distributed control and acquisition system has been developed that allows for fast expansion of any new device and feature. It will be briefly presented.

Speaker: Ruben Pieter De Groote (University of Jyvaskyla (FI))
