MOPTS002	Linac Energy Jitter Measurements with SPARK BPMs at ALBA	833

	At ALBA four Beam Position Monitors (BPMs) measure the beam position along the Linac to Booster Transfer Line. The BPM electronics (Libera Spark type) have been recently upgraded in order to be sensitive to single-pass beam detection. As a result, the position resolution measured in LTB BPMs has been increased by a factor 10 with respect to the former electronics. The increased resolution enables us to resolve the energy jitter of the Linac beam, providing an on-line measurement of the Linac energy during regular operation. In this paper a study of the Linac energy jitter is presented as well as its correlation with the jitter sources.

MOPTS095	Optimization of the Alba Linac Operation Modes	1086

	ALBA is a third generation synchrotron light source that consists on a linac, booster and storage ring. The linac is capable of operating in single (SBM) and multi-bunch injection mode (MBM). Since 2016 the Single Bunch Bucket Selection algorithm which runs in SBM, permits to inject on a selected bucket keeping the charge uniformity along the ring below 4\%. However when running in SBM a significantly lower transmission along the linac is observed, with respect to the one when running in MBM. Simulation efforts have been deployed in order to build up a reliable model of the ALBA linac which can reproduce the experimental measurements. In this paper we present the new simulation model that renders the experimental observations, and the new optimization procedure developed in simulations and tested in the real machine.

ALBA is a third generation synchrotron light source that consists on a linac, booster and storage ring. The linac is capable of operating in single (SBM) and multi-bunch injection mode (MBM). Since 2016 the Single Bunch Bucket Selection algorithm which runs in SBM, permits to inject on a selected bucket keeping the charge uniformity along the ring below 4\%. However when running in SBM a significantly lower transmission along the linac is observed, with respect to the one when running in MBM. Simulation efforts have been deployed in order to build up a reliable model of the ALBA linac which can reproduce the experimental measurements. In this paper we present the new simulation model that renders the experimental observations, and the new optimization procedure developed in simulations and tested in the real machine.
