Dear Colleague,

I would like to begin by wishing you a very happy and successful New 
Year. I hope 2026 will be a productive and inspiring year for your research

The next deadline for standard proposal submission will be *Monday 16 
February (midnight central European time)*.
DDT 
<https://www.ill.eu/for-all-users/applying-for-beamtime/directors-discretionary-time-ddt> 
or EASY 
<https://www.ill.eu/for-ill-users/applying-for-beamtime/easy-easy-access-system> 
access are available all year round.

Read the detailed information and instrument availability: 
https://www.ill.eu/for-ill-users/applying-for-beamtime/standard-access 
<https://www.ill.eu/for-ill-users/applying-for-beamtime/standard-access>

In particular, pay attention to the section*Beamtime allocation policy: 
"two-thirds rule"*
Proposals from non-member country proposers will only be guaranteed a 
chance of acceptance if they are part of a collaboration with at least 
two-thirds of the proposers coming from one of the Associate or 
Scientific Member Countries 
<https://www.ill.eu/about-the-ill/what-is-the-ill/an-international-partnership> 
of the ILL.

*Contact the experts!
*We strongly recommend to engage with facility staff or experienced 
users to refine the proposal  and increase its strength.

News on instruments
*Find the latest updates in the “Latest Instrumentation Developments” 
section on the webpage linked above.
In particular, please note that following the recent recommendation of 
the Scientific Council, ILL management has decided to *restore IN8 to 
100% operational status.*
In contrast, *D3 and D9 will remain at 50% operational time*, as per the 
current strategic and scientific priorities.

*Panel meetings:* 14-15 April 2026
*Scheduling period: *Second 1.5 cycles in 2026
*Autumn 2026 call deadline:* 15 September 2026

Scientific excellence is the primary evaluation criterion. However, 
providing complete and detailed information at the time of submission is 
highly beneficial, as additional factors—such as industrial relevance, 
the presence or absence of experimental reports, the proposer’s 
publication track record, or links to PhD projects—may also influence 
the assessment either positively or negatively.


************************************************************

    Once again, the ILL is offering a way for accessing beam time for
    projects that require a particular extended preparation period and
    request instrument beam time of a reactor cycle or longer. *This
    type of access is for the moment open only for PF1B, PF2 and FIPPS
    instruments.
    *
    Proposals must be submitted to the ILL *by Monday 16 March 2026*,
    via email to User Office <mailto:user-office at ill.eu> and meet
    certain conditions, specified in the dedicated webpage
    <https://www.ill.eu/for-ill-users/applying-for-beamtime/type-of-beamtime-access/ebta-proposals>.
    *You should equally fill in the attached EBTA-Exp_template and join
    it to your proposal.*

    EBTA calls are organised on a *yearly basis* for the instruments
    listed above. For the *2026 transition*, a *single EBTA call is
    planned for the spring round*.
     From 2027 onwards, the scheme is expected to follow a regular
    annual rhythm.


We very much look forward to receiving your proposals and to working 
with you in the coming year.

With our best wishes for a successful 2026,
The ILL User Office
