A custom-made instrument for differential thermal
anaivsts (DT A} of explosive materiale was designed and
built for routine uperations at Group GMX-3 This compact
mxtelis besed on the prototype developed by R oN Rogers,
Group GMX-2, who adapted DTA to explosive materials
DTA thermogiams are obtained with this apparatus on very
smitl ~amples, which reduces the explosion hazard The
main fetture of the apparatus is an expendable furnace assembly contained in a blast-shielded drawer This drawer,
the programmer, the ther mucouple reference, the microvelt amplifier, and the X-¥ recorder are assembled into a
relay rack for vase of operation by the analyst) Calibration
of the axes is described and a simplified procedure is desetoped for the accurate recording of DTA thermograms on
rpreprinted chart Ereegularities caused by faults compovsond munpalitie technique tre discussed, and ree+
crompendied methods are given to remedy etch situation
Phe appendixes contain a formal procedure for the peration of thag instrument with iluste wions of the apparatus,
schermitic diagrams gtaphs of temperature vs millivolt
output, and typical DTA thermograms produced by this inTrument (1th)
