SHMS User Group Issues General Discussion at Hall C User’s Summer Workshop August 5, 2008

Dr. Garth Huber, Dept. of Physics, Univ. of Regina, Regina, SK S4S0A2, Canada. 2 Excerpt from: Hall C Detector Design and Safety Review 6 February 2008 Are individual and group responsibilities clearly identified? We encourage management to urge the formation of a more formal SHMS collaboration. This should involve the proponents of the primary experiments that will get performed, the magnet design team, the groups who will build the individual subsystems, the experienced people who will integrate these subsystems into a working detector package, and those who will commission and operate the device.We encourage management to urge the formation of a more formal SHMS collaboration. This should involve the proponents of the primary experiments that will get performed, the magnet design team, the groups who will build the individual subsystems, the experienced people who will integrate these subsystems into a working detector package, and those who will commission and operate the device. As discussed below, the unusual timing of the planned completion of detector construction at least two years in advance of first operation of the SHMS will pose special challenges that could be met by a more formal SHMS collaboration, rather than the existing model of a user community.As discussed below, the unusual timing of the planned completion of detector construction at least two years in advance of first operation of the SHMS will pose special challenges that could be met by a more formal SHMS collaboration, rather than the existing model of a user community.

Minimal bylaws –Official steering committee, laying out procedure and terms of election by Users. –List of responsibilties [largely the same as the present Hall C User Committee]. Begin work on a more detailed commissioning plan –Draft made by steering committee? Special committee?

Helpful to have an elected Board to oversee issues and represent SHMS Users to Management. –Allison Lung and Rolf Ent have started periodic meetings between representatives of the User community and the12 GeV Project Management reps. Julie Roche presently represents the Hall C Users. –Selection of Board members via an election would help legitimize the Board members in the view of both the Users as well as Management. More formal organization might by itself be a way to ease the Hall C standing toward DOE.

A special set of Commissioning/Collaboration Experiments?? –Not desirable to put off detailed commissioning and optimization until the later high-precision measurements. –Special status for the first few experiments is probably helpful. –The real question is what should happen afterwards. –Still want to encourage experiments from external users, or people who want to run things “their own way”.

How the entity evolves past the SHMS commissioning stage (STEP 2) is perhaps the largest difference between a Collaboration and User Group.How the entity evolves past the SHMS commissioning stage (STEP 2) is perhaps the largest difference between a Collaboration and User Group. Review of PAC proposals and publications.Less beneficial: Review of PAC proposals and publications. Formal Membership List, Elected Board.More beneficial: Formal Membership List, Elected Board. Should anymember be eligible to participate in any experiment (as in Hall A)?Not clear: Should any member be eligible to participate in any experiment (as in Hall A)? SHMS Collaboration or User Group?

If a more formal structure is what people want, then a committee should be struck to put together a simple set of bylaws and circulate it for input.If a more formal structure is what people want, then a committee should be struck to put together a simple set of bylaws and circulate it for input. John Arrington is willing to be involved, which may be useful given his experience with all three halls, as well as the JLab User Group..John Arrington is willing to be involved, which may be useful given his experience with all three halls, as well as the JLab User Group..
