Description As part of the GT Herschel Program CHESS we detected for the
first time hydrogen chlorine in a protostellar shock, L1157-B1
(Codella et al. 2011). One of the most surprising results of this work
was the lack of enhancement in the abundance of HCl with respect
to dense interstellar clouds, implying that HCl is not enhanced by the
passage of a shock. This means that either chlorine is not sputtered
during the passage of the shock (unlikely as Si is sputtered) or that
HCl is not the main reservoir of clorine in shocked regions (unlike in
dense interstellar clouds). In this proposal we propose to observe
HCl in a sample of shocked regions in order to determine whether
this result is unique to L1157-B1. We stress that given the weakness of
the HCl emission in shocks and the strong atmospheric water absorption
at the requested frequency (626 GHz), the present experiment
cannot be reasonably performed from ground, making of Herschel
OT2 the last chance to reach the present goals.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
