BLIP operations 03-8-11

The BLIP facility is currently operational at 117.5 MeV, with the weekly average beam increasing to 100.9 µA. Operations time has risen to 166.4 hours, marking the highest this year. Isotope production for Sr-82 has resumed due to higher demand from secondary users. Recent research irradiation for Cu-67 was conducted, while irradiation of LBNE targets continues. Investigations into Ga target leaks are ongoing, and alternative cladding materials, such as Ta and W, are being explored. Future trials will address beam profile issues to enhance target performance.

  1. BLIP operations 03-8-11 Status – running at 117.5MeV BLIP weekly average beam increased to 100.9µA,. Operations increased to 166.4 hours, highest this year. Isotope production of Sr-82 has resumed, as secondary user has ramped up demand. Research irradiation for Cu-67 took place yesterday and irradiation LBNE targets downstream of the isotope targets continues. Operations issues Investigation of cause of Ga targets leaks continues. Literature indicates that the resistance of the Nb cladding to attack by Ga significantly declines at temperatures above 400 0C. The mechanism is stated to be dissolution of Nb in Ga, rather than liquid metal embrittlement. This seems consistent with our lack of observation of cracking. Linac tried without success again to get the octupole beam profile working in order to reduce power density on target. There is now some understanding as to the cause of the problem. Instead a broader Gaussian profile was achieved and another trial with the Ga target is planned. We have begun investigating alternate cladding materials including Ta and W, as well as the possibility of flame spraying the cladding interior with alumina as a protective layer.
