The invention relates to a Co-base target made of a sintered powder, having a restrained amount of oxygen, and a producing method thereof. A debris deflector mounted within the main housing between the water and debris inlet and the water outlet is sloped downwardly towards the debris outlet and has a plurality of parallel slots that permit water to pass from the water and debris inlet to the water outlet. The signal-to-pulse conversion module converts the N-bit signal at the intermediate frequency into a pulse signal of M-bits at the radio frequency.
