Status of procurement:

Formal specifications are under preparation in agreement with DGS-RP-RW to define the following:

137Cs source:The source is described as part of the irradiatorPreference is given to purchase a standard source (7.4 or 16.65TBq)Possibly the 16.65TBq- One source of 16.65TBq is currently available (delivery of 1 month)

Irradiator:Users opted for a single source irradiator (2009)- Single and multiple source irradiators are standard in industry

Attenuator:The mechanism of the attenuator can be provided by industry- The curvature of all filters will be simulated and submitted to approval of users- Production and adjustment of the lead lenses can be done by CERN- The outer layer (4th) will remain accessible for special needs.

Retrieval of the new irradiator

Experience shows that companies recently established can also rapidly disappear and generate unpredictable costs.

For this reason our specification document will request commitment to:- receive prompt service,- announce the cost for regular maintenance,- plan the recuperation of the irradiator at the end of its service life.

Retrieval of our BA102 irradiator will also be included in the specification document.
