Quick start guide

Welcome to ID-10 BEATS. Below is a coarse overview of the most important steps to setup and perform your first scan. To keep to page simple but provide all information needed, links to in depth descriptions are provided in the corresponding sections.

Note

The beamline is setup for your experiment at the start of the beamtime together with the beamline staff. This includes energy adjustment and mounting detector and optics. Most of the times, there will be little to change from one scan to the next, besides aligning the sample. Ask the beamline staff before changing any beamline setting.

Getting started

The beamline control GUI allows to control the in-vacuum instrumentation in the beamline front-end, optics hutch, and experimental hutch.

Here are things users should be comfortable doing during their experiments.

In particular, you might need to adjust the configuration of:

  • One or more of the beamline slits

  • Attenuator system

  • search the hutch and open the shutters

  • adjust the sample on the stage

  • start a scan

The heartpiece of beamline operation is the beats-qt GUI.

If it’s not already started or gets closed accidentally, it can be started from a linux console on the control computer (e.g. by pressing ctrl + alt + t) and typing

$ beats-qt

The BEATS beamline GUI allows to #. display the machine status and parameters. #. launch the BEATS Beamline vacuum GUI. The vacuum GUI is used to open the shutters of the beamline. #. launch the BEATS Experimental GUI. This GUI controls the sample manipulator and detection systems.

Beamline vacuum GUI

To be able to acquire meaningful data, you need to have X-rays on your sample. Therefore, the shutters need to be opened at least. Open the shutters only when needed and you want to measure (also to protect your sample). Openening the shutters can only be performed after the hutch has been searched.

To open the beamline light path, the shutters must be opened in the following order:

  1. Radiation shutter.

  2. Photon shutter.

  3. Combined stopper.

Note

It is only allowed to open the beamline shutters once the hutches have been searched. You will see a red button besides one of the shutter if opening is not allowed.

Warning

Before opening the beamline shutters for the first time, verify with your local contact the setup of the beamline (slits, attenuator, …).

Search the hutch
