Using ISPyB During your Experiment

You can use ISPyB to monitor the beamline during your session; from R22 while having lunch or from the comfort of Ridgeway House.

Getting Started

Start by logging in to ispyb using your fed ID and password.

Webcams & Beamline Status

If your visit is currently active on the beamline, you will see the “i15-1 Webcams & Beamline Status” title when you select your visit. Click this title to reveal the webcams and the beamline status.

Beamline Status

Ring Current	The current in the ring, in mA. This should be between 295 and 305 in standard operation.
Refill	The storage ring is constantly losing electrons, and so some new ones are injected every 10 minutes. This is the time in seconds until the next refill.
Front End	The “front end” is broadly where the x-rays leave the storage ring, and enter the beamline. The front end needs to be open to get x-rays into the optics hutch.
EH3 PSS	The EH3 PSS tells you whether the experimental hutch is searched; in a secret code. 65535 means the hutch is searched (and this status will be green). Anything else and the hutch is not searched.
EH3 Shutter	The EH3 shutter is the main safety shutter that blocks the x-rays from entering the experimental hutch.

Webcams

We have two webcams on the beamline, which are viewable through the web interface. You can ask your local contact if you’d like them focussed elsewhere.

Log

The next item on this page is the log. This shows all of the events on the beamline; which are mostly data collections. More details about the data collections can be seen below.

Data Collections

All of your data collections appear in ispyb automatically, and you can access various metadata directly through the web interface.

Sample

Clicking the link here will take you to the sample, and show you the sample information and all of the data collections that have been collected against this sample.

Group

Most data collections on I15-1 involve more than one detector. In the language of ispyb, each detector has its own data collection, and they are collected together into a data collection group. The list of entries on your data collections page is actually a list of data collection groups, and the group shows many there. You can click the link here and it will expand the view to show every data collection in the group.

Auto Processing

A synopsis of the automatic processing that is applied in dawn is also supplied in the form of a jupyter notebook. You can click the Auto Processing bar, then Logs/Files, and then download the processed nexus file directly, or view the jupyter notebook.
