Abstract We have developed a new detector using thin lanthanum bromide crystal (32×3mm) for use in X-ray astronomy. The instrument was launched in high altitude balloon flight on two different occasions, December 21, 2007, which reached a ceiling altitude of 4.3mbs and April 25, 2008 reaching a ceiling altitude 2.8mbs. The observed background counting rate at the ceiling altitude of 4mbs was ∼4×10−3 ctcm−2 s−1 keV−1 sr−1. This paper describes the details of the experiment, the detector characteristics, and the background behaviour at the ceiling altitude.
