To avail Pelletron Beam time, one must submit Beam time proposals by filling one of the Beam Time Request (BTR) Form (in prescribed formats, see below) with in the stipulated dates (May 31 for July AUC / November 10 for December AUC ) to the AUC Convenor . If invited, they should present it before the Accelerator User Committee Members during the AUC Meeting on July 6-7 or December 17-18
BTR-1 : Beam Time Request for Fresh Proposals
BTR-2 : Beam Time Account (BTA) for Ph.D Students from Universities/Teaching Institutions
BTR-3 : Request of UFR Project (funding) and Beam Time
BTR-4 : Beam Time Request for Ongoing Proposal
to defend in AUC meeting
you are planning to get a beam
time only, not funds
by the Principal Investigator / any collaborator / student
you are planning to get both beam
time and funds
(Applicable for University Users only)
BTR3 should be forwarded by your University Registrar
by the Principal Investigator / any collaborator (but not from IUAC)
(student presentation not acceptable in case of sanction of funds)
you are planning to get a subsequent run
of an already availed run(s) of a sanctioned Project
Please submit all detailed reports and copies of published papers related to the run already availed
is not required
getting a complete Beam Time
Account for a student
Submit detailed Thesis Proposal
by the concerned student only
(The guide may be present in the meeting)
Note : Simultaneous submission of BTR2 & BTR3 will not be entertained.
Accelerator User Committee (AUC)
The AUC evaluates the beamtime proposals / presentations in the AUC meetings on July 8 and December 19 of every year.
The decisions are thereby informed to the respective Principal Investigators.
Beam time scheduling
Beam time is scheduled by the Beam Time Scheduling Group of IUAC;following the sanctioned list of experiments and as per the requests made by corresponding users.
Corresponding users are informed about their beamtime ahead of the schedule.
One IUAC Personnel (LEC) is assigned to help the user during the experiment.
User Presentation is arranged at the end of the experiment to get the user feedback.
Similar procedure is being followed for funding User Facility for Research projects (UFR) as for beamtime.
A University project, if approved by AUC, gets standard funds for three years. Each year the corresponding funds are sent to the relevant University subject to submission of satisfactory academic report & audited utilization certificate of the project for the previous year.
At the end of 3 years , a project completion report is required alongwith the financial expenditure status.
For any UFR related queries, contact.
The 15 UD Pelletron at IUAC is a vertical tandem electrostatic accelerator. Negative ions from the ion source are pre-accelerated, mass analyzed and injected at energy of 250 to 350 KeV into the accelerator. At the terminal they are stripped to various charge states (q) by foil or gas stripper. These positive ions then get repelled by the terminal to gain further energy which is then energy analyzed by an analyzer magnet (1.8 m radius) and can be delivered in seven beam lines by using a switching magnet.
The energy of the accelerated particle beam available depends on the charge state (q) of the ion and the terminal potential V (in MV)
