Baby cyclotrons are known as a hospital equipment be cause they are build to fulfill the medical proposes, in general, they can afford until 4 targets to activated most of

Also the device dimensions where 3.6 x 2 x 2 m3 for the acceleration d´s and inner shielding. And the room has to have at least 7 x 5 m2 only for the cyclotron and another 6 x 5 m2 for the synthesis lab. But the very concerning issue is the weight of the entire system, only in inner shielding it has 37 tons and the magnet alone has a weight of 11 tons the full system is over

This cyclotron produce protons of 9.6 millions of electron volts (MeV) of energy with a maximum current of 50 μΑ, the target is made of oxigen to transmute to fluor. In this activation process there are some particles going out the path of the main beam so they have to be stopped by the inner shielding as to warranty 10 μSv/h at 1 m from shleding and 1 m

In our experiences, the utmost importance matter in a Cyclotron is the Quality Assurance

from floor. Also the magnetic regulation permit 1 G at 6 m from the center of the D´s

In Venezuelan experience the first installed cyclotron has the following characteristics:

**8. Baby cyclotron characteristics** 

radioisotopes needs to do PET studies

• Generated beam for activation: H +

• Activation Product: 18F- (fluorine ion). • Running average activity: 800 mCi • Activation efficiency: Greater than 60%

• Material to Activate: H218O

**8.1 Venezuelan medical cyclotron** 

Program in which must be include:

3. Radiation Safety Aspects

• Safety Interlocks • Audible alarm • Luminous alarm

• Processing unit connection

2. Mechanical and performance aspects and

**8.1.1 Electrical aspects that have to be under control are:** 

**8.1.2 Mechanical and performance aspects to be under control are:** 

In a broad approximation, we can say that:

1. Electrical Aspects

• On/off switches • For operation • For Emergency • Failure Interlocks

• Selfdiagnostic

• Radiofrequency • Driver

50 tons

• Energy required for the activation: 9.6 MeV • Output Beam minimal current: 50 μ A
