In situ data collection on VMXi
Read all of the below carefully on how to access the beamlines.
There are no pre-scheduled visits as you may have been used to in the past. You can ship samples to us following the dates in the table above, and when the dewar arrives at Diamond we will then schedule a visit for the appropriate duration.
From Run 3 of 2021, Diamond resumed 6-day running with Tuesday as a Machine Day. Therefore User beam is available between 9:00 on Wednesdays through to 9:00 on Tuesdays.
As we continue to prioritise work on COVID-19, we are now operating a responsive access mode. Sessions for shipments on-site will be scheduled after arrival, prioritising COVID-19 related work and taking into account user requests and beamline availability.
All users requiring training or information should get in touch with the local contact associated to their visit. Please write to firstname.lastname@example.org if no local contact has been assigned yet.
Industrial users (proprietary access) should liaise with email@example.com as normal.
Remote interactive data collection (academic/industrial)
Standard (responsive) remote access to all beamlines. If you have a challenging problem (for example, new crystals to test where diffraction quality is unknown, difficult phasing problems or require microfocus beam) then an interactive remote access visit is likely appropriate. For these visits we will schedule your visit once we have received your samples at Diamond.
Automated unattended data collection (academic/industrial)
If you have a crystal system that meets straightforward requirements then the automated unattended data collection service is for you.
You simply provide us with some limited information when creating your shipment and samples in ISPyB and we handle the rest, with data collected as soon as reasonably possible. This is the most flexible way for us to schedule beamtime currently and places no constraints on your time to be available for collection.
Currently, unattended data collection offers a choice of 4 recipes:
|Prioritises completeness/resolution and collects 2 x 360° sweeps, 1st at chi=0 and 2nd at chi=30. Each sweep uses half the expected lifetime dose.||20|
|Phasing||Multiple sweeps are collected using different chi/phi values at your chosen energy, using a lower transmission to maximise anomalous multiplicity and completeness. The total dose used is half the expected lifetime.||20|
|Ligand||Prioritises speed of data collection and collects a single sweep, 360° dataset. This single sweep uses the full expected dose and is a good choice for weakly diffracting crystals.||25|
|Stepped||Prioritises resolution and conducts a stepped transmission scan. Each 360° scan increases transmission by a factor of 4.||10|
Limited on site access and supported remote access
We are trialing both on site access and staff supported remote sessions booked in advance of samples arriving at Diamond. A supported remote session will have heavy involvement of a staff member on your session, perhaps for a challenging phasing problem, training new staff or students, or for testing new features of the beamlines.
To request either on site access, or a supported remote session please get in touch with the relevant Principal Beamline Scientist and firstname.lastname@example.org more than 2 weeks before the sesison is required and we will confirm whether the request is feasible. If you're request could be dealt with by multiple beamlines, then email email@example.com in the first instance and we can forward to the most appropriate Principle Beamline Scientist.
On site access will also be subject to the Diamond site wide restrictions, see our user information and working protocols.
Once time is scheduled you must inform us no less than 10 working days before the experiment if you no longer wish to use this time so we can make best use of available beamtime. Where feasible you may be able to reuse this time later in the allocation period. If you cancel with less than 10 working days notice the time will be counted towards your allocation.
Mail-in service (industrial only)
For industrial mail-in service please discuss your needs with the industrial liaison team.
Long wavelength beamline I23
All EU and NI users, arranging their shipment with DHL in ISPyB should be aware that they cannot create an airwaybill in ISPyB and should contact firstname.lastname@example.org (Academic MX), email@example.com (Industrial Users) or EBICadmin@diamond.ac.uk (Academic EBIC) respectively, and follow the appropriate guidance below.
|Organiser||Academic Users||Industrial Users|
|Origin||UK||ISPyB & DHL||User's courier||ISPyB & DHL||User's courier|
|EU & NI||ISPyB & DHL||User's courier||EU/ RoW ISPyB & DHL||EU/RoW user's Courier|
|Rest of World||N/A||User's courier|
Those highlighted in green are our current preferred method of shipping. Due to recent changes these rules are subject to change at short notice, so please check current advice before arranging your shipment.
For all routes we need all container and sample information completed before shipment to Diamond.
For automated unattended data collection, we simply need the information required for data collection parameters for all samples to be provided in UAS and ISPyB as outlined in the webpages here.
For a responsive remote access or industrial mail-in visits we need you to complete the short questionnaire in the Shipment Comments field when shipping your samples to help us configure the beamtime schedule.
On ticking the Responsive Remote / Mail-in session option (see image below) the questionnaire in the shipment comments requests the following information (please answer after each question as appropriate):
This information will be reviewed at point of scheduling and adjusted as appropriate to maximise the use of the available beamtime.
Please note until relevant information is provided and containers and samples are created, shipped and have arrived at Diamond we will not be able to schedule your beamtime.
We now schedule by the hour for remote access and mail-in sessions based on the information provided by yourselves at the shipment stage. Samples for responsive remote access will be scheduled once they are on-site, and have information completed on samples in ISPyB. Where feasible we may be able to make slots available the same week and we will contact you to set these up. Equally if demand is high at any time we may need to contact you to allocate the earliest available slot outside of the period you have provided with your shipment for your availability. Scheduled users will receive notification of time automatically from UAS. Please contact us immediately if there are any issues with the allocated time. We will have limited opportunities to adjust the schedule and your time may need to be deferred to a later slot if you cannot use the offered time.
Samples for automated unattended data collection will be collected at the earliest possible available slot.
Scheduling for on site, or supported remote session will be done in advance, by contacting firstname.lastname@example.org and the relevant Principle Beamline Scientist. This may be in advance of the samples sent to Diamond, in this case you should send samples to against that registered visit.
As with any scheduled beamtime, in UAS you will need to add team members who wish to collect data and complete the ERA including samples for this session. You will have only shipped samples to us that have already been approved at the proposal level (see above) and consequently if samples you add to the visit are green your visit should automatically be approved and we can load your pucks. New unapproved samples should not be added at this stage.
For enquiries (except for I23, VMXi and industry) prior to any beamtime please contact email@example.com who will coordinate a response to your questions.
Once a visit has been scheduled and a local contact has been assigned please liaise with them first (see UAS for your local contact).
