Openable Storage Cell

In order to maximize the available luminosity for the double polarized experiments at ANKE the storage cell for the polarized internal gas target has to be opened during beam injection to avoid beam losses and to be closed again afterwards. The commissioning of this openable/closable storage cell has been successfully conducted.

The cell operated in a very stable and reliable way. A desired beam intensity from COSY has been achieved, when passing a pre-cooled stacked beam through the cell. The gain factor in density of the (hydrogen/deuterium) gas target of the order of 5 has been demonstrated, which is close to the expected figure. In a titanium cell a high degree of polarisation of hydrogen (85%) and deuterium (70%) has been obtained.
