Governance
The management of the service will be carried out through the IISTA Secretariat, which has adequate staff for the management of accesses and will be supported by the OTRI of the UGR, for the application of accounting procedures for the application of public prices. Thus, accesses from the institution itself will be managed as subscriptions between the units of the UGR. On the other hand, the accesses and by researchers belonging to other organizations will be managed through the system of order forms enabled by the OTRI, for the establishment of cooperation agreements. For this purpose, the tables currently in force will be applied, which will be updated to include the new equipment. In any case, the opportunity and convenience of access, especially in cases of multiple requests coinciding in time, will be managed by the scientific committee of the IISTA, which advises the IISTA management team on the different technical and scientific aspects of its daily operation.
The management of the service will be coordinated by the Research Transfer Office, OTRI, of the University of Granada, UGR, which will support the agreements that will be established for access to the equipment, both by national researchers and by organizations and companies interested in its use. On the other hand, continuous cooperation will be maintained with the Center for Scientific Instrumentation, CIC, of the UGR, which will be able to complete IISTA’s offer and contribute to the improvement of the services offered. On the other hand, given IISTA’s vocation to offer Access services via TNA, a permanent coordination will be maintained with ATMO-ACCESS, which currently coordinates the TNAs related to ACTRIS, ICOS and IAGOS. In this regard, the TNA pathways foreseen in ATMO_ACCESS will be explored, in particular the virtual one, where the PI of the proposal is responsible for a task within the access modalities work package. Also, given the participation of the PI of the proposal as a member of the Management Committee in the COST PROBE and COLOSSAL actions, coordination will be maintained with them and their short stay research programs (STSM), which will be extended to other COST actions with which links are maintained, such as InDust or ADOPT.
As for publicity channels, in addition to the IISTA’s own web page, the channels provided by the UGR, through the OTRI and the CIC, as well as those provided by ATMO_ACCESS and the COST actions mentioned above, will be used.
Protocol for accessing the common service
In the general framework, access to the different service offers will be made through the IISTA Secretariat, which has staff trained for this type of management. In this sense, the support of the UGR’s OTRI is essential, through which the management of the services is materialized, by means of an agreement between the parties based on the service request form prepared by the IISTA Secretariat. The OTRI is in charge of issuing the necessary invoice for the payment of the requested services. Parallel to this administrative process, the IISTA Management Team, with the support of its Scientific Committee, will assess the viability of the requested service and will make decisions in the event of simultaneous requests.
Transnational accesses will be made following the protocols and procedures established in ATMO-ACCES.
In the IISTA web page, the service costs are currently detailed and will be updated in the future, which as indicated above will be charged through the OTRI of the UGR, through the preparation of the corresponding service request form.
