For an electron bunch with 10 pC charge and 3.7 MeV kinetic energy, the energy spread was 0.5% with a shot-to-shot stability of 0.05%. After focusing the bunch by a pulsed solenoid lens at 140 mm from the middle of the lens, the focal spot was 40 lm with a shot-to-shot stability of 5 lm.

Photo Gun is the secret weapon for all your photo processing needs!

No more time consuming, repetitive work! Simply drag and drop a picture, a hundred or thousands of photos, to the drop-window and select operations you want to apply to them. With a click of the 'Save Results' button all processed photo-files are stored in a separate output folder.

You can perform the following operations:

• Resize photos to make them more suitable for emails, blogs, websites, social networks, your personal use or for your business
• Adjust brightness, contrast and saturation to enhance the light and color balance
• Add professional touches to your photos and apply 'Vignetting', a creative effect, to draw attention to the center of the frame
• Add watermark to prevent unauthorized use and/or copyright text or company logo with a customizable transparency level and other parameters. You can also use this operation to merge your photos
• Crop to cut away unneeded image parts
• Rotate to change the image angle
• Mirror to flip the image vertically and horizontally
• Blur to hide some of the details of your photos (different levels of blurring available)
• Add Borders for a decorative look using different frame thicknesses and colors
• Swap the RGB-channels;
• Apply the Histogram optimization to automatically improve photos taken under similar conditions
• Binarize the images, using the threshold value and produce the monochromatic results
• Grayscale to convert color images into black-and-white ones
• Invert the photos
• Convert the file formats into/from JPEG, PNG, TIFF, BMP, XPM, PPM, including the full range quality compression of JPEG ranging from 1% to 100%
• Give new names to your photos
• Change the order of operations to achieve the best result
• Save the operation flows as presets, if you will need them over and over again
• Preview all images at each stage of the applied operations by clicking the eye symbol on the flow thumbnails, with retina-ready graphics.

Abstract

This contribution describes the latest milestones of a multiyear program to build and operate a compact $-300\mathrm{kV}$ dc high voltage photogun with inverted insulator geometry and alkali-antimonide photocathodes. Photocathode thermal emittance measurements and quantum efficiency charge lifetime measurements at average current up to 4.5 mA are presented, as well as an innovative implementation of ion generation and tracking simulations to explain the benefits of a biased anode to repel beam line ions from the anode-cathode gap, to dramatically improve the operating lifetime of the photogun and eliminate the occurrence of micro-arc discharges.
