- Neon Indicator lamp replacement • Physics Forums
To replace a neon indicator lamp in an old flash gun with an LED, the circuit operates with a voltage range starting at 240V and going up to 350V, connected in series with a 1 5Gohm resistor across a charged capacitor The user has a 4AA battery pack available, which can work with rechargeable batteries down to 4 8V There is uncertainty regarding the design of the 'ready' lamp circuit
- Undergraduate thesis topic ideas in medical physics
Flash RT There's some evidence that when radiation is delivered at very high dose dates (above about 40 Gy s), toxicities that are induced at more conventional dose rates can be avoided There's a big question right now about why this is, and lots of interest in modifying conventional machines and devices to deliver and measure radiation at high dose rates
