During the last year we have installed and commissioned a second x-ray pinhole at ALBA for redundant and alternative beam size measurements. Here we report the issues we encountered and compare the ultimate PSF of both pinholes at ALBA. We also report on the first steps of a computer vision and machine learning application for pinhole beam diagnostics.
We have trained an artificial neural...
Multiple systems of photon diagnostics are adapted at SESAME, in order to measure beam size and to observe the beam profile in various positions. One of the systems is the In-Air X-ray Detector (IAXD), which primarily depends on high-exposure imaging of the residual high energy x-rays that escaped after the photon absorber on the ends of the bending magnet ports. In addition to that, the...
Several Visible Light diagnostics have put in operation, more than 1 year after the start of the EBS commissioning. The Visible Light extraction system, with its first mirror in UHV and a chicaned transfer line, has been completely and optimally aligned to obtain distortion-free light in a dedicated laboratory at 9m from source point. This allowed to characterize this light in different means,...
A BPM calibration-readout system composed by a Libera Spark and a Pilot-tone generator has been installed at ALBA. In this talk, results on stability and position measurement will be reported. A comparison of performances between this readout system and other Libera Elettronics, will also be presented.

In this presentation the actual work on the bunch purity measurement at PETRA III will be reported. The system is based on small area XAPDs used as detector in a time correlated single photon counting measurement scheme. At first improvements of the analog electronics of the detector head will be shown. An introduction to the test setup and placement at the PETRA III storage ring and the...
SOLEIL Synchrotron has an upgrade plan to replace its storage ring by a new one based on multi-bend (7/4BA) achromat lattice. To fulfil the new tight requirements, most beam diagnostics will have to be replaced, or at least refurbished and improved. Among them are the X-ray Beam Position Monitors (XBPMs). Located on each beamline front-end, they enable to measure the position of the photon...
Synchrotron upgrades at Diamond Light Source and elsewhere are being undertaken to increase the X-ray brightness. A side effect of this is an increase in power that may be intercepted by X-ray beam diagnostics. Of particular concern are front end XBPMs, often the first component along the beam path. Diamond currently uses a temperature interlock to prevent damage to XBPMs in the event of a...
