【 摘 要 】

A new windowless gas target has been developed in Mexico. It is a supersonic gas jet flow produced inside a vacuum chamber which can be coupled to a regular beam line in an accelerator laboratory as a differential pumping system brings the pressure of the gas target system down to a microTorr, or better, at the connecting stage. In this work, we present the system as it was designed and constructed as well as the first results using air, Nitrogen and Argon.
