A wide variety of MeV ions can be focused, enabling imaging of charge collection efficiencies with sub-µm resolution. By TRIBIC (similar to Transient Current Technique – TCT) basic detector parameters can be extracted. The facility is equipped with 6.0 MV EN Tandem Van de Graaff and a 1.0 MV Tandetron, equipped with two ion sources that provide a wide range of ions from hydrogen and helium to heavy ions, and number of experimental end-stations.

At the RBI Accelerator Facility users will be able to study:

• in vacuum and in-air IBIC imaging of charge collection properties using protons of up to 10 MeV with 1 μm resolution and heavier ions on demand; time resolved IBIC (lateral and frontal TRIBIC);
• real-time controlled damaging of small detector areas using protons or heavier ions. For such studies users will have on disposal a heavy ion microprobe and other end stations depending on the actual objectives of the proposed work.

Transnational access information

Who is eligible and how to apply for transnational access is explained at the EURO-Labs web site. RBI Tandem Accelerator Facility (RBI-AF) is one of the research infrastructures within the Work package 4 (WP4): RI’s for deterctors. The first step for potential user is to contact the facility coordinator for the facility user is interested in with brief details of a proposal. This step will ensure that the proposed experiment is doable and that potential users are eligible for TA support before going through the formal application procedure. The selection of user groups and experiments is primarily the responsibility of the facility coordinator, acting with approval of the User Selection Panel (USP). USP for RBI-AF is the same as for all the other RIs within the WP4.

The infrastructure can accommodate in average 3 user projects per year (total 12 user projects), in average 42 hours per project (total 504  hours of operation). Each user project experiment would assume 5 days spent at the infrastructure (about 8 hours per day) and includes the necessary preparatory work like sample mounting on specific sample holders, beam irradiation and if possible data analysis. At the end of the experiment the users will receive all the measurement files and instructions how to proceed with the analysis. Local staff will assist the users even after the run in data analysis to obtain usual IBIC or TRIBIC output data (like for example charge collection efficiency spatial maps) in usable formats.

Each experiment includes full support of local staff in experiments and data processing. For each experiment it is expected that one to two users will be present at the infrastructure and be actively involved in all the work phases together with locally assigned staff.

Reimbursement information

The users of the RBI Tandem Accelerator Facility may receive subsistence expenses only if their project has been approved within the EURO-Labs Transnational Access rules and the costs eligible for reimbursment have been agreed with the RBI Facility coordinator in advance. The costs for one to two external users per project may be reimbursed, depending on the project needs and availability of funds.

Costs for travel and accommodation can be reimbursed according to the rules of Ruder Boskovic Institute (RBI) and the Republic of Croatia. Name of the user(s), arrival and departure dates and other data should be provided in advance to enable entrance to the Institute and for booking of travel and accomodation. User expenses will be managed and paid by RBI. The expenses cover:

• Accomodation: dormitory or hotel/hostel near the Institute reserved in advance by the RBI for user(s)
• Travel: the most economical form of transportation which is practical, including economy class air travel, second class train, public transport (including bus) may be reimbursed. Car travel may be reimbursed in some cases (subject to agreement). In case of air travel, RBI will book the ticket. The user should submit boarding cards after the travel within one week. All persons entitled for reimbursement need to have travel order issues by RBI.
