Calculating the Magnetic Field for Accelerating Protons in a Cyclotron

Given parameters:
- Cyclotron oscillator frequency = 10 MHz
- Radius of dees = 60 cm
- Charge of a proton = e = 1.6 x 10^-19 C
- Mass of a proton = mp = 1.67 x 10^-27 kg

Formula to use:
- Cyclotron frequency = (qB)/(2πm)
where q is the charge of the particle, B is the magnetic field, and m is the mass of the particle.

Step-by-Step Solution:
1. Convert the cyclotron oscillator frequency to angular frequency:
ω = 2πf = 2π x 10 MHz = 2π x 10^7 Hz

2. Substitute the given parameters into the formula:
2π x 10^7 Hz = (eB)/(2πmp)

3. Solve for the magnetic field, B:
B = (2πmpω)/e
B = (2π x 1.67 x 10^-27 kg x 2π x 10^7 Hz)/(1.6 x 10^-19 C)
B = 0.66 T

Therefore, the magnetic field required to accelerate protons with a cyclotron oscillator frequency of 10 MHz and a radius of 60 cm is 0.66 T. The correct answer is option D.
