Report on the GASP User meeting of January 9, 2001 and of the PAC meeting of Feb. 5-6, 2001

Padova, Feb. 28, 2001

In the GASP User meeting of January, 2001 we have been discussing the 14 proposals to be presented to the following Legnaro PAC, for a total request of 82 days of beam time.
7 of the proposals were requesting GASP in Configuration I (with BGO inner ball).
5 were requesting GASP in Configuration II.
2 were possible in both Configurations.

The PAC of Legnaro met on Feb. 5-6, 2001.
The following 6 proposals have been approved:


The number of days assigned to GASP experiments is 34.



Padova, Dec 7, 2000

Next GASP USER Meeting

Dear Colleagues,

the deadline for proposals at GASP is approaching (January 12, 2001) with the Legnaro PAC meeting scheduled for Feb. 5-6, 2001.

As usual, before submitting the proposals, we would like to have a meeting with the people interested in doing experiments at GASP in order to organize accordingly the work around the array.
GASP has been working, in the last period, in Configuration I (with the BGO inner ball).

Users are therefore invited to a one day

GASP-USER MEETING

TUESDAY, JANUARY 9, 2001
at Legnaro (starting from 10.00 a.m.)


If you intend to submit a GASP proposal to the Legnaro PAC for the next period, you should present it and/or discuss its feasibility at that meeting.
If you are not able to come, you should in any case send a short abstract and contact some local people working at GASP who can present it.


Looking forward to see you in Legnaro or to hear from you

With best regards

Santo Lunardi


Report on the GASP User meeting of June 6 and of the PAC meeting of July 10-11, 2000

Padova, August 30, 2000

In the GASP User meeting of June 6, 2000 we have been discussing on 11 proposals to be presented to the following Legnaro PAC. Of these 9 have
been then submitted to the PAC for a total request of
61 days of beam time.
Six of the proposals were requesting the ISIS silicon ball and all of them GASP in Configuration I (with BGO inner ball).

The PAC of Legnaro met on July 10,11, 2000.
The following 7 proposals have been approved:


The number of days assigned to GASP experiments is 49.
Other 6 days have been assigned to the experiment "Search for wobbling bands built on stable triaxial shapes in 138,139Nd (S. Lunardi, Padova)" scheduled in the previos period but which suffered from problems with the 48Ca beam.

Next GASP USER Meeting

Dear Colleagues,

the deadline for proposals at GASP is approaching (June 16, 2000) with the Legnaro PAC meeting scheduled for July 10-11, 2000.

As usual, before submitting the proposals, we would like to have a meeting with the people interested in doing experiments at GASP in order to organize accordingly the work around the array.
GASP has been working, in the last period, in Configuration I (with the BGO inner ball).
A small array of neutron detectors has been installed at forwardangles, which replace 6 detectors of the BGO inner ball.
The neutron detection efficiency is ranging from 4 to 6% depending on the reaction kinematics.
In the last two experiments the neutron detectors have been used in the study of proton-rich nuclei, giving excellent results.


Users are therefore invited to a one day

GASP-USER MEETING

FRIDAY, JUNE 9, 2000

Results of the Legnaro PAC meeting of January 31-February 1, 2000

Padova, March 30, 2000



In the last meeting of the Legnaro PAC 13 proposals (out of 22) have been presented requesting the use of GASP for a total of 76 days of beam time.

The following 7 have been approved:


These experiments, for a total of 34 days of beam time, will be performed before summer 2000.


Padova, December 21, 1999

Summary of the Last GASP USER Meeting

In the GASP user's meeting of December 16, 1999 we have discussed the experimental proposals to be presented to the next Legnaro PAC (deadline January 12, 2000).
As in the previous meetings, the goal was to discuss the feasibility of the proposed experiments and to plan the most efficient use of the array as, for example, a possible change of configuration from I to II.
The number of proposals presented was 16, with 15 requesting beam time at the next PAC meeting while one was considering to build a recoil decay tagging system at the RMS focal plane for future experiments with the coupled system GASP+RMS.
Two of the proposals are for commissioning of new instrumentation:
a) the new neutron detectors which will substitute the forward part of the inner ball,
b) improvements of the performances of the recoil mass spectrometer.
Of the remaining 13 proposals 8 have a spokesperson coming from a non italian istitution whereas the other 5 come from italian institutions involved in the GASP collaboration.
The total number of days that should be requested to the PAC is 77 with only 11 of them in configuration 2. It is therefore realistic to think that the configuration 2 will not be installed in the first part of the PAC period, but could be at the end, according to the number of approved proposals and in connection with new proposals in configuration 2 approved by the following PAC.
We have anyway still 5 experiments, approved in previous PAC, that have to be performed for a total of 23 days. Two of them are already scheduled for end of January (exp. 99.65, D. R. Napoli) and beginning of March (99.44, R. Broda).



Padova, November 16, 1999

Next GASP USER Meeting

Dear Colleagues,

as you know, the next Legnaro PAC meeting is scheduled for January 31-February 1, 2000 and the deadline for proposals is January 12, 2000.
As usual, before submitting the proposals, we would like to have a meeting with the people interested in doing experiments at GASP in order to organize accordingly the work around the array.
The array has been working, during 1999, in Configuration I (with the BGO inner ball).
Most of the experiments have been performed using the silicon ball ISIS and the Recoil Mass Spectrometer.
A new focal plane detector has been recently installed in RMS which has proven to work extremely well in the reactions 90Zr+90Zr at 368-376 MeV and 40Ca+92Mo at 190 MeV.
At the moment we do not plan any change of configuration since all the experiments approved by the last PAC are requiring the configuration I. Three of them will be scheduled in the first months of the next year.
Depending on the number and type of new proposals we are anyway ready to change configuration during the next period and this is why we encourage users to submit proposals also with configuration II.

Users are therefore invited to a one day
