Reports
1. Beam-time schedule changes
z The NP0702-RIBF17 (Kobayashi) BT (beam time) was extended for 3 days to compensate for thedays lost in the primary and secondary beam tuning. The BT was, however, terminated as of July 1
at 4:00, before the newly allocated end time on July 1, 9:00, due to vacuum trouble with BigRIPS.
Nevertheless, with the spokesperson’s consent, this BT was regarded as a completed BT.

z

Due to this trouble, the NP0906-RIBF16 (Kobayashi) BT that was to follow right after was canceled.
Also, all following BTs scheduled through July 19, except for a RILAC-standalone BT, weredelayed for 2-3 days.

2. Status of the PAC meetings in the first half of FY2010z

7th NP-PAC: PAC report approved by RNC & CNS directors.

z

2nd In-PAC (Industrial Program Advisory Committee): PAC report sent to RNC director.

Discussions
1. The minutes of the 34th meeting were approved.
2. NP-PAC reportzUpdate of the approved proposal:
The PAC recommends enabling the users to update their approved original proposals if theexperiments can run by using the beams projected to be run in 2011. In line with thisrecommendation, it was decided to announce details in the next call for proposals which will
be made in September. As another issue, discussion was initiated on re-scheduling alreadyapproved BT dates, such as when the primary beam current is increased and/or theproduction cross-section is revealed to be larger than that assumed in a proposal.

zChange in grading scale used to evaluate proposals:

The PAC has decided to use a new grading scale that applies four different categories fordeciding the A and B rankings of approved experiments. In fairness to past proposals, it wassuggested that already approved backlog experiments should be re-evaluated using the newgrading scale by the time of the next PAC (scheduled for December). It was decided to refer
this to the PAC.

z

Follow-up evaluation of completed experiments:

In line with a suggestion from the PAC, it was decided to require users to make progress
reports—until the first publication is submitted and/or the project is considered to becomplete—to the PAC on the status of experiments one year after their run.

3. Schedule of 8th NP-PAC meetingz

The 8th NP-PAC meeting will be held December 3-4 (or Dec. 3-5) just before the Halo25 conference
which will take place December 6-9 at Hayama.

z

Prior to posting calls for proposals, schedules will be announced via the mailing list and web site,in particular to enable proposal updates.

4. Coming second half-year BT allocationz

The SHE experiment (RILAC standalone) will be allocated Sep./4-Oct./22 and Jan.-Mar./31.

z

The service for education (AVF standalone) will be allocated four times during Nov.-Jan. The test
BT for a new chamber prepared for this service will be arranged after the proposal is reviewed.

5. Distribution of the minutes of MT committee meetingz

The draft minutes are currently distributed to all experiment spokespersons, liaisons, and the PIs of
the RIBF-related teams/laboratories as well as the MT committee members. The RIBF-UEC hasrequested distribution of the draft version to all RIBF users as well, but the MT committee believes
that only the officially approved version of the minutes should be made public and therefore
distribution of the draft version will remain the same as it is now. Since the UEC chair is invited as
an observer, the UEC chair is welcome to prepare and distribute a memo on the proceedings
regarding any matters that the UEC chair believes should be notified to all RIBF users.

z

The minutes so far are only made available as hardcopy. The possibility of also providing them aselectronic files that can be downloaded from the web site is now being considered.

6. Next MT Committee meetingz

Depending on the situation of the vacuum problem with BigRIPS, an extraordinary MT Committee
meeting may be held on Friday, August 20, 2010.

zThe next regular MT Committee meeting will be held on Friday, September 17, 2010, from 13:30 to15:00.
