Major Changes to Submission Procedure

For these calls there are major changes to the design submission process to align with the introduction of the CORNERSTONE terms and conditions:

All design submissions, even those that are supported by EPSRC funding, must agree with the terms and conditions. Under no circumstances will we accept designs without agreement with the terms.

Therefore, we strongly recommend that the terms and conditions are pre-authorised by your institution prior to the mask submission date.

In order to be eligible to submit a design you must first notify us of your intention to submit a design using the online form found using the link below. This is in order to enable us to prepare the necessary paperwork and plan the fabrication process effectively. The deadline for the notification of intention to submit is Friday 18th January 2019.

www.cornerstone.sotonfab.co.uk/work-with-us/intention-to-submit-form

Under no circumstances will we accept any design submissions for which we have not received prior notification of intention to submit a design.

After completing the intention to submit online form, when you are ready to submit your mask design on or before Friday 1st March 2019, follow the link below to the CORNERSTONE website mask submission page:
