FIG. 1.

Schematic of measuring the response of MCP to positive, negative, and neutral oxygen from spray target.

Image of FIG. 2.
FIG. 2.

Picture of ion pits detected on CR-39. Pits of (a) oxygen and (c) hydrogen ions along their spectral tracks. Pits in (b) is zoomed picture of “zero point” showing similarity with the (a) oxygen and (c) hydrogen ions pits.

Image of FIG. 3.
FIG. 3.

Calibration of MCP for O, O and O ions. (a) Correlation of counts on MCP to the particles counted on CR-39 for O and O ions together is shown. (b) Response (i.e., counts/particle) of MCP is shown for O, O and O ions. The blue square points show the average response of MCP to the O.

Image of FIG. 4.
FIG. 4.

Calibration of MCP for H. (a) The correlation of counts on MCP to the particles counted on CR-39 is shown. (b) Response (i.e., counts/particle) of MCP is shown for H.

Image of FIG. 5.
FIG. 5.

Distribution of a signal at the “zero point” on MCP. Two distinct different Gaussian functions are necessary to fit the data: one is a signal due to the x-ray, and another due to the energetic neutral particles.

FIG. 6.

Comparison of calibration data from Ref. and data presented in this paper.
