Water cluster project (data analyzed by R):

1. Data collection: Water cluster (nanoparticle < 10nm) beam intensity are synchronized with a periodic mechanical chopper, and recorded by multichannel scalar (MCS) with long acquisitions for statistically- meaningful results. Raw data (MCS spectra) are time resolved intensity of water clusters and contain the information of cluster speeds which are Gaussian distributions. 2. Normalization data: A program is written to import MCS spectrum, and which can be pre-normalized by subtracting the mean value of MCS profile from every channel, setting a range normally -1 to 1. A cosine function is fitted to the pre-normalized MCS profile by using the least squares methods. Two ranges

(depleted region when chopper turns off the beam and un-depleted region when chopper turns on the beam) were selected to normalize the MCS spectrum to the range [0,1]. 3. Water cluster speed: The known profile ‘Vollmer profile’ is fitted into the normalized MCS spectrum and two parameters can be finally extracted to obtain the average speed of water cluster. A small variation estimation program in R to implement a statistical re-sampling technique known as ‘bootstrapping’. 4. Final results: Two sets of data (pure water cluster speeds and doped water cluster speeds with HCl) are measured. We concluded that a statistical table shows the water cluster fragments during the electron ionization, and results were published on JCP.
