PASS (Platform for managing user access to ACTRIS ServiceS) is the access management platform optimised to enable and ease the management of the Transnational Access (TA) process in the frame of the IRISCC project. Implemented as a web tool by the Service and Access Management Unit of the ACTRIS Head Office (SAMU), leader of IRISCC Work Package 8 “IRISCC TA and VA access management”, PASS has been made available to IRISCC. The existing tool has been customised to organise and control the central management and selection of user requests to access services provided by the facilities/platforms/installations via IRISCC. The customised PASS for IRISCC was initially released in November 2024 and described in project's internal Milestone 10 - 1st release of the optimised TA management tool. It was then updated following the reviews of the application and review forms received until March 2025 (version v2.0). Final optimisation of the PASS to accommodate the management of the Strategic IRISCC Access Programme as described in Deliverable D7.2 – Strategic IRISCC Access Programme was done in April 2025 (version 3.0). The web tool PASS can be reached at https://passactris.smapply.io and potential applicants can access it via a link from the IRISCC Catalogue of Services released in April 2025 – the signel-entry point for IRISCC services. This report of the Deliverable D8.1 “Optimized IRISCC TA management tool” (DEM – Demonstrator, pilot, prototype) does not describe in detail the workflow or technicalities of the customisations made on the PASS but offers views to the web interface. It shares screen shots of the PASS homepage, the IRISCC TA Calls programme including the IRISCC TA Call for Fast-Track, and the TA admin, applicant and the reviewer portals. The IRISCC TA admin portal and dashboard allow management of different calls/programs in parallel.
