The CARIBU-matic project: automation for the transport of radioactive beams from the CARIBU source*

The CARIBU source at the ATLAS user facility provides beams of radioactive isotopes made from the spontaneuos fission of a 252Cf source. Such radioactive beams allow our users to carry out their cutting-edge experiments. However, the stardard approach at extracting and transporting the beams to the user's end stations is based on time-consuming expert-driven manual tuning methods. In this talk, we will give an update on the CARIBU-matic project, which is an effort to automate components of the radioactive beam delivery process through machine-learning methods and hardware improvements. Results from an early implementation of the automation of CARIBU beam transport via Bayesian optimization, using Xopt [1] and Badger [2], will be presented.
