4 MEDICIS & Building 179

MEDICIS
The irradiation permit has been cancelled today by Anne Funken following the last collection of Sm-153 that happened over the week-end and has been shipped this morning.
Edgars, Thierry and Arfan are at the Heidelberg hopsital now waiting for the package to arrive and start the radiochemistry steps there.
Some YETS activities will start already from today with the discussion about adding the KROMEK into the CCM as well as with Christophe coming to add a timing for the water and interlocks.
Visit of the LV parlement this afternoon.

Next monday we will stop the hardware permit.

Speakers: Charlotte Duchemin (CERN SY/STI/RBS), Edgars Mamis, Joachim Vollaire (CERN), Laura Lambert (CERN), Manikanta Elle (KU Leuven (BE)), Matthieu Deschamps, Patricija Kalnina (University of Latvia (LV)), Ralf Erik Rossel (CERN)

b.179

• Barriers for IBDRS works still blocking the gas point, but these will be moved. Finishing up concreting then will move the barriers behind the small concrete wall - this should hopefully give enough space to then access the gas point and change bottles.
• Antenna has been unplugged! Not by me, I went yesterday and it seems it was severed likely from the works involving removing all the vegetation from the hill. So this likely happened a few weeks ago, so far no complaints from anyone, so it seems it likely wasn't anything important...at least that we know of yet.
• Annual testing of filters starting today until thurs
• DAIKIN intervention on acclimitisation system tomorrow
• Visit friday with Dartmouth uni students
• Several palettes of targets to be moved to ISR today end of day

5 Targets, Schedule and Physics

Speakers: Hanne Heylen (CERN), Isabel Frank (CERN), Matthias Alexander Grasser, Simon Thomas Stegemann (CERN)

Physics

• During the day on GPS, offline PAC experiments were carried out using ¹¹¹ᵐCd implanted at GLM. The aim was to investigate the structure of several solid state materials, for example Bismuth Ferrite and various perovskites, the latter being relevant for solar cell applications. On the first day the isomer to ground state ratio was slightly too low, but this was resolved on the following days. The experiment was restricted to daytime operation only, because RP needed to be present for the manipulation of implanted samples, a precaution introduced after incidents earlier this year during another beam time. This went very smoothly, both from safety and experiment point of view, and the experimental teams went home with a bunch a good data.
• On HRS, the in source laser spectroscopy run on Ni was completed. The campaign was challenging overall, but in the end the team succeeded in collecting several good new data sets, both for decay spectroscopy and for in source spectroscopy. The final weekend focused on bismuth isotopes for IDS and ISOLTRAP, beginning with in source laser spectroscopy and later moving to precise decay spectroscopy, which is of interest for medical applications involving ²²⁵Ac. After the proton beam stopped, the team continued for one additional shift on ²⁰⁹Tl. This was made possible thanks to a last minute, but very appreciated, change in RILIS, without which these final measurements would not have been possible. Despite several difficulties, the team still managed to obtain good data.
