Hi Sam,
ISIS do not run open days themselves, but the events and visits team run general public open days where you have the opportunity to visit some of the facilities that the Rutherford Appleton laboratory has to offer.
Our next general public open day is on the 9th June 2011.
Please let me know how many people you would like to bring and their rough age range and I will add you to the provisional guest list.
Many Thanks
Will
