On HRS, neutron-deficient Tm beams were delivered to COLLAPS for laser spectroscopy measurements. This required a LIST target which is more complex to prepare and operate. Following earlier attempts, the goal was to measure ¹⁵⁰Tm and ¹⁵¹Tm. Yields appeared promising at the start of the run, but the target performance degraded over time. As a result, only data on ¹⁵¹Tm could be collected, with ¹⁵⁰Tm ultimately out of reach. Despite this, the users were relatively satisfied with the outcome.
