Halogen Radiant Roaster
I have used a perforated stainless drum with propane for about 16 years with good results. I do use perforated ceramic blocks between the flame and the beans, which creates a barrier, but also transfers heat as an infrared radiator as the ceramic blocks heat to bright red at times. I am a big fan of the perforated stainless, number one because you can turn the temperature on a dime, and number two it releases all of the chaff and smoke as it roasts.

And your ET probe is placed... where ?
I measure the ambient temperature of the roaster at Bean level. I have used a long stem dial thermometer at times two measure temperature in the bean Mass, but it does not help me that much as long as I control the roaster temperature. All temperature readings are essentially approximation that you can learn to depend on at various points. No one has come up with a functional way to measure internal bean temperature while roasting, although we toy with the idea I'm a small Bean size capsule with a temperature sending unit, but could not find one that would tolerate the Heat.
