Summary

  • Manufacturing of single carbon alveoli units of 18 different types for the whole barrel was
  • completed. Spare units of each type were produced in amount of about 10%.
  • Special mold is ready for the mass production of front inserts at IHEP. Production rate is

about 100 pcs./day.

  • Module plates and support feet as well as the support beam were produced and delivered to

IHEP; pre-assembling test is in progress .

  • Addendum 3 and Addendum 4 to the Collaboration Contract which are necessary to solve

custom formalities and perform delivery of Batch #2 of the components and devices for the pre-series slice assembling were written and sent to FAIR for the final approval and signing.

  • We plan to finish all the tests during couple of weeks and hope to get signed Addenda
