We'll use an auto head light bulb to offer a load rather than the ion gauge tube filament and https://www.vapingplay.com/nectarine-tangerine-cream-by-dr-fog-fruit-and-cream-series-100ml-shortfill-75vg-e-liquid-juice-vape for the grid degas (not at the identical time). The one ones I've seen with electron bombardment degas are a few outdated Veeco models - the RG-840 (and https://forum.tmipodcast.com/index.php?action=profile;u=150945 RG-84 which is mainly the same). However, https://www.vapingplay.com/blueberry-doozy-vape-co.-fifty-50-10-x-10ml-e-liquid-50vg-vape-juice-all-strengths ion gauge controllers are readily out there surplus for a small fraction of their new price. The only part which is non-trivial is the electrometer amplifier which must deal with extraordinarily small values of ion present.
A small stepup transformer is used to spice up the AC heater voltage to a worth that can be rectified with common diodes. I used a Stancor one hundred fifteen V to 12.6 VCT power transformer in reverse for initial assessments. These exams will even require a 100K resistor https://www.vapeenough.com/candy-king-on-ice-strawberry-watermelon-bubblegum-100ml and 100K pot (to simulate the emission present path) and https://www.vapingplay.com/strawberry-menthol-chuffed-100ml-e-liquid-70vg-vape-0mg-juice a a hundred ohm resistor (to supply a current path between the 2 grid pins until a second head gentle bulb is used to act because the grid).
Install the 100 ohm resistor or your second auto head gentle bulb between the two grid pins. Attach the auto head light bulb to the filament pins of the ion gauge tube connector. For the needs of this description, we assume that the controller is appropriate with the everyday Bayard-Alpert ion gauge sensor such as the Lesker G075TN which has the next specs: - Filament voltage: Three to 5 VAC. A gauge of this sort can be perfect for the HeNe and Ar/Kr ion lasers, and others that are pumped down and maintained beneath a certain pressure over long periods of operation or previous to seal-off of the tube.
The enter to the meter on "High" can then vary from about zero to 15 mV with a recent 9 V battery and still attain 10 mV with an previous drained one. The brand new American cartridge was designated Cartridge, Ball, donginws.co.kr Caliber .30, Model of 1906. The M1906 cartridge is best recognized as the .30-06 Springfield round, used in many rifles and https://www.vapingplay.com/chuffed-to-bits-tangy-apple-100ml-e-liquid-70vg-vape-0mg-juice machine guns, and https://www.vapebill.com/e.b.-design-bc5000-disposable-vape-device-black-winter remains to be a well-liked civilian cartridge to the present day.
I discovered an MKS Instruments Baratron mannequin 227A rated at 1 Torr full scale in the trash and decided to see if it worked.
