DESIREE is a double electrostatic storage ring designed for experiments
with merged beams of positive and negative ions, such as studies of mutual
neutralization between two singly charged ions. It can also be used for
single-beam experiments like measurements of atomic lifetimes or investigations
of the physical properties of biomolecules.
DESIREE consists of two rings, each with a circumference of approximately
9.3 m, with one common straight section where the beams of the two rings
are merged. The rings will be housed in a single vacuum chamber/cryostat with
double walls. With the use of cryogenerators, the rings can be cooled to
a temperature of 5-8 K.
The project was funded by the Knut and Alice Wallenberg Foundation and the
Swedish Research Council,
and it is estimated that DESIREE will have its first beams some time during the
autumn of 2010.
Documentation about DESIREE can be found in the Design Report
and in our contributions to
EPAC04 and EPAC06.
