Characterization of the AGGIE Gas-filled Separator
The AGGIE gas-filled separator has been installed at the Cyclotron Institute at Texas A&M University and is now in routine use. Named Albert Ghiorso's Gas-filled Ion Equipment and formerly known as SASSY II and later SASSYER, the separator has a D v Q h D v configuration and is currently used for nuclear reaction studies and online chemistry experiments. This manuscript describes the separator and experiments to measure its transmission, which was found to be ≈ 22% using the 164 Dy( 40 Ar, xn ) 204− x Po reactions. Additionally, an investigation into AGGIE's ability to measure beam luminosity with a new, diamond detector was performed. The response of the diamond detector was characterized relative to the traditionally used silicon detector. The diamond detector was found to be overall suitable for luminosity measurements with a notable improvement in radiation hardness as evaluated based on the centroid, spectroscopic resolution and count rate of the implanting ions, thus minimizing potential for downtime while replacing detectors during an irradiation.
