That should not be a problem with most of the designs I have seen. Of course, you do not want to run the line power up too high for the tool since you might...
Also, no matter which gun/gamma you run, you should check the bottom of tool with a meter while tool is powered up to ensure no voltage reaches explosive...
I have heard of it where the tool could be powered up too high when downhole to where it would set he gun off before. But it was nothing that was done on...
There is a design where the gamma gun can fire dual polarity, but it is inherently more dangerous. The safest approach is to run the tool on positive, and...
Syd, Alf, All, I have been trying to imagine why a gun would shoot with too high of positive tool voltage and here's what I came up with... Diodes have a...
Correction, The reverse breakdown voltage for the 1N4007 is 700 Vrms and 1000 Vpeak. It's also referred to as the DC blocking voltage. Thanks, Chuck...
I doubt that would be the source of accidental firing. The diode would be a 1N5061 or equivalent, and there would be two of em at least. More likely, it was...
Syd, It's the "or equivalent" part of your statement that can cause problems. The equivalent diode for the 1N5061 is a 1N4005. It's Vr is 420 Vrms or 600 volts...
The dual polarity guns are designed to shoot with either polarity, an inherently dangerous situation. They accomplish positive shooting with an overvoltage...
John, depends on the application. I am making the assumption you want this for production logging purposes. My experience has been that with roller ...
The answer to the question really depends on the well design and to a certain extent its condition. In fully cased vertical wells with relatively large bores...

Is it just a power supply problem? Does the tool draw more than the computer power supply can furnish? Looks like there ought to be a workaround if that is...
