The user community I

Photon facilities

 Synchrotrons and Free Electron Lasers (FELs)

 Light of highest brightness

 Typical range from infra-red to Xrays

 Facility size hundreds of meters

 About 15 synchrotrons in EU (ESRF + national)

FELs, even 10

times brighter

 SLAC/Stanford, DESY/Hamburg, FEL/Spring-8/Japan, PSI/Villigen

 Membrane proteins; microscopic movies of chemical reactions

Neutron facilities

 Complementary

 Similar user community

In EU >> 30’000 visiting users /y

 Large overbooking (≥3:1), low chance to be accepted

 Important to minimize administrative load (Local user offices)

On-site visits

 Short duration

 In part spontaneous (keep that attraction)

 Part-time users

Decentralized structure (compare e.g. to CERN)

 Manifold research fields

 Many data sources facilities

 National character of facilities, report to own governments

Zoo of research areas

Archaeology, chemistry, materials + analytical sciences, life sciences

 Physics is minority

Linking element is common use of large facilities (not science field) !

(4)

What are the IT requests?

Huge datasets

 Novel 2D detectors, quantum leap in data quality, but also data volumes

 multi-image techniques (tomography, lens-less imaging)

 molecular movies at FELs

 ‘Petabyte’ ‘normal’ unity; time over for ‘hard-disk in the trouser pocket’

Trans-facility experiments

 Standardize proposal procedures on EU scale

Remote data access

 analyze data remotely at facility

 combine datasets taken at different facilities

 clouds (commercial, community-based)

 respect confidentiality restrictions

Remote experiment access

 basic: passive online access to measured data

 advanced: active control

PR Issues

 Improve corporate identity

Incorporate confidentiality aspects

 High competition, especially structural biology

 Time-window structured access to experiments and data

Rely on existing local user office structure

 Great experience

 DIY (Do It Yourself) operation

 Users: manage their personal entries

 User offices: supervising; manage authorizations

Base system on professional authentication standard

 Shibboleth, federated Single-Sign-On System (SAML), widely used

 special photon / neutron user federation

 only one identity provider

 supervising by local User Offices

Umbrella prototype concept

Concept

 Unique user identification on EU scale

 Hybrid information storage

 No automatic cross-facility information exchange

 Multi-level identification (maximum autonomy to facilities)

 Waterproof but slim data protection system

Embargo vs. post-embargo period

Embargo (first 3y): confidentiality, access to own team only

 Post-embargo: free access, possibly via registration

Standardized / automatized access rights

 manual central authorization impossible

 1‘000s of experiments, 10‘000s of users

Identity by Umbrella

 Unique, EU-wide user authentication

Keep Role of proposal as organizing element

 Users convene for a short time slot for performing an experiment

 Principal investigator / main proposer

 Who participates in experiment, has access right to data

 Proposal officially accepted by facility, PI is official contact

 PI defines experiment participants (practically existing WUO tool)

Use case: Remote data access

Hybrid concept (central and federated)

Answer to conflicting requests:

Efficient technology

Confidentiality

Consequent distinction of authentication and authorisation

EPH characteristics

Present situation:

 heavy administrative load on users

 no synchronization in call for proposals

 no EU proposal standard

 start always from scratch in spite of iterative character

Umbrella answer: subdivision into different parts

 Statistical

 Facility

 General (science)

Umbrella solution characteristics

 Federated proposal storage at facilities

 Compatibility with existing proposal handling

 Federated hybrid user database

 No Cross / trans-facility actions

 User: significant reduction of administrative load

 Facilities: no change in proposal handling work flow

Demands at large photon / neutron facilities very clear to IT responsibles

 Unique user ID

 Remote data and experiment access

 Need for user and facility friendliness

 Very large number of visiting scientists: Need slim and efficient system

Reduced excitement on management (and user?) side

 Resources

 Confidentiality

 Scientific competition

Overlapping IT communities

 Large facilities and universities (educational sector)

 Large facilities and university labs

Umbrella as prototype

 common web portal

 Slim solution, no top down organization, self service elements

 Build on existing infrastructure, clear topology, no double worlds
