Need for an extension of AD hall
F. BUTIN / ELENA collaboration
Four main goals for an extension of AD hall:
1. Relocate the existing workshop2. Provide short term storage space for
experiments3. Accomodate for ELENA ring and
experimental areas4. Host the magnetic horns test bench

Accomodate for ELENA

ELENA ring will sit here:Need to remove quite a bit of stuff

Accomodate for experimental areas

What AD hall will look like after ELENA’s installation

Rough proposal of Gbar area
F. BUTIN / ELENA collaboration
To be adapted with extraction line and with Gbar needs
![Page 17: AD/ELENA (B193) Experimental hall conditions](https://reader035.vdocuments.site/reader035/viewer/2022062409/5681458c550346895db277db/html5/thumbnails/17.jpg)
Work conditions in AD environment
To access and work in AD hall: Valid CERN access card Safety training level 1 and 2. Radiation + electrical training
mandatory Dosimeter (medical certificate) Specific AD area access right (when
operational) No particular EPI, except during
heavy handling operationsVisits are possible and regulated

![Page 18: AD/ELENA (B193) Experimental hall conditions](https://reader035.vdocuments.site/reader035/viewer/2022062409/5681458c550346895db277db/html5/thumbnails/18.jpg)
General rules for AD experiments
40 cm shielding around exp area. Access controled. No access inside shielded zone during run
Linac case to be treated with great care
CRs are located in bdg 93, racks are in 193
Radiations (eg. generated by Linac): shielding to be put in place to reach <3mSv/h at working/circulation places
Visit circuit nearby: < 0.5 mSv/hF. BUTIN / ELENA collaboration

Specific constraints with GBar
Electronics cooling: max 10 kW released in air, how much with water ?
Use of gases (N2, Ar, Ne, SF6, O3), no cryogens: Distribution ? Extraction ? Need of ODH detection ?
Test stands ? Assembly area ? Clean room ?
Number of racks that can be accomodated is limited (about 25)
Position of laser hut is tricky (location/stability)…

Conclusions 2 ELENA project is on its way Space reserved for at least 1 new
experiment and corresponding control room, pending approval of AD hall extension building
Waiting for official approval to launch serious integration work for Gbar in AD/ELENA environment
