MuX Collaboration Meeting

Monday 5 Nov 2018, 09:00 → 22:00 Europe/Zurich

Auditorium / WHGA001 (Paul Scherrer Institut)

The first muX collaboration Meeting is organised at PSI on Monday November 5, 2018. The aim of the collaboration meeting is to discuss the main aspects of the developments done since the beginning of the muX project in 2015 and the future upgrade plans. Special emphasis will be put on the plan of hosting Miniball at PSI during 2019. In this respect the Miniball collaboration and the nuclear spectroscopy community are warmly invited to participate to the meeting and present ideas for possible measurements which go beyond the muX experimental programme. Open slots have been reserved in the Discussion section for presenting new proposals. Please send an email in case you have a contribution.

16:15 Muon capture experiment at PSI

In the talk we observe our previous experience at the PSI muon facility, namely high precision gamma-spectroscopy with negative slow muons on the μE-4 and μΕ-1 beams with HPGe – detectors and with isotopically enriched targets (solid and gas). Such experiments could be divided in to three parts: • Doppler profile of gamma-lines following OMC (angular correlation with neutrino) • Partial capture rates (for double beta decay, as an example) • Muonic X-rays (electronic catalogue www.muxrays.jinr.ru) We also plan to discuss the possibilities to continue such investigations, and some new ideas in future.

16:35 Radioisotope separation at MEDICIS

The CERN MEDICIS facility (MEDical Isotopes Collected from ISolde) consists in a replica of the CERN ISOLDE front end followed by the original Leuven ISOL dipole magnet [1]. Target-ion-source units made at ISOLDE are irradiated parasitically behind the standard ISOLDE target and then brought out of the irradiation area with a monorail system until it can be placed on the front end. Radioisotopes are then ionised, separated, and implanted in a substrate. The main aim of the facility is to support research into novel medical radioisotopes (e.g. the work on terbium radioisotopes at PSI [2]). Since its first radioisotope extraction in December 2017, the CERN MEDICIS facility has been increasing its production, demonstrating in particular the ability to also process imported samples, such a neutron-activated Er-168/169 from ILL (Grenoble, France). Based on the success of this endeavour, further collaborations are planned with external partners, such as the cyclotron facility ARRONAX (Nantes, France), which will allow CERN MEDICIS to continue operation during the CERN Long Shutdown 2 (Nov 2018 - Apr 2021). Besides its medical radioisotope program, CERN MEDICIS is now considering also supporting other research activities if beam time is available. As such, it might become possible to enrich samples with mixed isotopes, to purify materials activated somewhere else, or even to produce radioisotopes of interest to the muX collaboration. In this contribution, I plan on presenting the CERN MEDICIS facility, its current achievements, and how the installation of the laser ion source in the coming months can impact the facility.
