checking out my probes which I found tonight after they had been lost in a corner of my office for at least five years. Found them when I was looking for something else. For those not familiar with sexing probes they are used to determine the sex of snakes. He is a Gray banded kingsnake (Lampropeltis alterna). Gray banded kingsnakes like other kingsnakes and milksnakes have some immunity to rattlesnake venom and may include other snakes in their diets. "Bandit," in captivity, eats only thawed frozen rodents. Gray banded kingsnakes are native to west Texas and eastern New Mexico. Photo by Frank
Testing a NaI(Tl) probe I got lying around for some time. Using documentation from the company that build these probes, Scionix, I was able to make a voltage divider and solder it to the tube socket. Later I will put it in a proper housing with BNC sockets and a mu metal shield against the Earths magnetic field, which can influence the performance of the probe by bending electrons in the photomultiplier.
Testing is done with a Cs-137 doped spark gap lying on the workbench.
I use my old Hameg 15 Mhz scope to view the pulses. It is fine for general electronics, but the steep pulses from the PMT are difficult for the scope to display properly. I need to get a better scope or just put a RC filter in line with the probe to lengthen the pulses.
The other day I discovered this bee in the act of discovering. Taken with a Canon 60mm USM Macro lens. Type L for a better view.

Samantha, once jilted by her high school sweetheart Jake during Snowcoming, returns home to honor her football coach father, whos retiring, and runs into Jake, now a famous quarterback. Although its awkward, their obvious chemistry is still there. Later, after seeing the library needs updating, Samantha asks Jake to use his celebrity as a draw for a Tailgate at the Library fundraiser. At the successful event, a nosey reporter probes Samantha about Jakes future in football, and lets it slip that Jake is leaving town. Stunned, Samantha wonders if Jake will allow his career to fumble their romance once again.
