To avail Accelerator Beam Time, one must submit beam time proposals by online filling one of the Beam Time Request (BTR) Form with in the stipulated dates (May 15 for July AUC / October 15 for December AUC ). Offline submissions will not be accepted. If invited, they should present it before the Accelerator User Committee Members during the AUC Meeting on July 5-7 or December 16-18
- 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
- BTR-5 : Beam Time Request for Low Energy Ion Beam Facility
| OPTION | WHAT TO SUBMIT | HOW TO DEFEND IN AUC | DOWNLOAD |
|---|---|---|---|
| If you are planning to get a beam time only without funds | BTR-1 Form | Presentation by the Principal Investigator / any collaborator / student | Download |
| For getting a complete Beam Time Account for a student | BTR-2 Form. Submit detailed Thesis Proposal | Presentation by the concerned student only (The guide may be present in the meeting) | Download |
| If you are planning to get a both beam time and funds (Applicable for University Users only) | BTR-3 Form, BTR-3 should be forwarded by your University Registrar | Presentation by the Principal Investigator / any collaborator (but not from IUAC) (student presentation not acceptable in case of sanction of funds) | Download |
| If you are planning to get a subsequent run of an already availed run(s) of a sanctioned Project | Submit BTR-4 Form Please submit all detailed reports and copies of published papers related to the run already availed |
Presentation is not required | Download |
| For Low Energy Ion Beam Facility | BTR-5 Form | Presentation by the Principal Investigator / any collaborator / student | Download |
| For Low Energy Ion Beam Facility with Funds/High Energy | Both BTR-5 Form & BTR-3 Form | Presentation by the Principal Investigator / any collaborator / student | Download |
| For Low Energy Ion Beam Facility and High Energy without funds | Both BTR-5 Form & BTR-1 Form | Presentation by the Principal Investigator / any collaborator / student | Download |
Note : Simultaneous submission of BTR2 & BTR3 will not be entertained. Proposal submission is online only, offline forms will not be accepted.
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.
The decisions are thereby informed to the respective Principal Investigators.
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.
UFR Project
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.
.Energy & Beam Available
The 15 UD Pelletron at IUAC is a vertical tandem electrostatic accelerator. Negative ions from the ion source are pre-accelerated E(inj), 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)
E (MeV ) = ( q + 1) V + E(inj)
With Pelletron and Superconducting Linear Accelerator (Linac) typically 70% more energy gain can be achieved.
Accommodation
Hostel and Guest houses are available on the campus. Booking has to be done in advance for convenience and visit has to get approval before actual arrival. A canteen and other facilities are available.For accommodation booking, contact academic[at]iuac[dot]res[dot]in
