STM32F103- How Can I Start and stop ADC with timer trigger?

Hello,
I have used a timer for triggering ADC for sampling per 20uS and use DMA to transfer 100 sample to the array.
 I suppose that the total time of converting and sampling time for ADC is about 2uS. So at each 20uS I can transfer 10 samples to the array with DMA.
I want to know that does the ADC stop the conversion at the end of 20uS or it continues the conversion and transferring the data to the array until it fills the whole array ?
Is it possible to force the DMA to transfer the converted values to the zero index of the array at the start of each triggering?

I dont know the order of transferring the converted values to the array with DMA at the start of each triggering?
 
Regards
Hamed
