The Johnson lab kept busy this summer attending Gordon Research Conferences throughout the northeast. Olga successfully chaired her second GRS at the Molecular Interactions and Dynamics seminar at Stonehill College in July. Both Olga and Joanna presented posters at both the GRC and GRS. The next week, Steph, Fabian, Patrick, Chinh, Helen and Nan drove up to the University of New England for the Vibrational Spectroscopy GRS and GRC. They had a great time and even met up with some Johnson lab alum! Photo credit - Jamie Stearns
A 2014 Science paper on the "Vibrational spectral signature of the proton defect in the three-dimensional H+(H2O)21cluster" was recently highlighted by the Department of Energy as part of their Basic Energy Sciences program!
Johnson Lab alumni had a successful run at the 64th annual ASMS conference on mass spectrometry and allied topics. Etienne Garand (now a professor at Wisconsin) received the ASMS Research Award for young faculty and Andrew DeBlase (now a postdoc with Tim Zwier and Scott McLuckey at Purdue) received the Postdoctoral Award. Congratulations Etienne and Andrew!

Johnson group members also held demos for New Haven area students as part of Yale's Chemistry Pathways program and participated as judges in the 22nd Annual New Haven Science Fair for K-12 students in the New Haven area.
After a succesful run as co-chair at the MIC GRS, Olga is preparing to chair the upcoming Molecular Interactions and Dynamics Gordan Research Seminar this July at Stonehill College in Easton, MA.
First year graduate student Nan Yang joins the group. Welcome Nan!
Joe and his wife Liz welcome their daughter Isabel to the world. Congratulations Joe and Liz!
Congratulations to Chinh for being awarded the National Science Foundation Graduate Research Fellowship for his proposal titled Systematic Capture and Structural Characterization of Proposed Intermediates in Homogeneous Catalysis!
Olga gave a contributing talk at the 251st ACS National Spring Meeting on characterizing the solvation shell of hydronium and hydroxide water clusters.
Over the past couple of months, the Johnson group has made some pretty major strides in the lab!
Our next generation machine, dubbed "the mini-machine" has come on-line. Even at a fraction of the size of our other instruments, the mini-machine can get down to comparable pressures and has great mass spec resolution, proving that "bigger isn't always better"! The mini-machine has also been used to test new capabilities, including a new way to record both mass and vibrational spectra using a PicoScope which allows us to bypass our old LeCroy o-scopes and boxcars.
T2 has also had some big changes recently. A second retro-reflectron was added to the back of the machine in order to give T2 double resonance capabilities. Additionally, one of our old imagers has been reinstalled onto the end of T2 and is now used to image the ion beam after it passes through the length of the machine. It makes it readily apparent how much the enizel lenses and deflectors affect the beam's trajectory!
Not to be left out, Tinman has also gotten a new capability! A make-shift glove box has been added to the front end in order to better store and prepare air sensative samples.
