Electron Cyclotron Resonance (ECR) Magnetometry. 330 $aThis book describes the first ever antimatter free-fall experiment, known as ALPHA-g, which measures the effect of Earth?s gravity on antimatter atoms. The effect of gravity on antimatter has been a subject of speculation for decades and experimental measurements have been a long-term goal of the field. The experiment found that it does indeed fall down, and this represents a first step toward precise measurements of gravity on antimatter. Any observed difference, no matter how small, would have a profound impact on physics. This book presents major contributions to the ALPHA-g experiment. In particular, the author developed precise magnetic field measurement techniques and led an extensive campaign to characterize magnetic fields in the ALPHA-g experiment, a key enabling factor without which the experiments would not have been possible. The author was also one of the leaders of an effort to design and install new antimatter traps in the apparatus that will be required for future measurements. The book shows the big picture of the work in the context of the wider field, and gives clear and concise descriptions of the experimental protocol, the required supporting measurements, and hardware developments needed for this measurement and for those in the future. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5061 606 $aExotic atoms 606 $aAtoms 606 $aMolecules 606 $aGravitation 606 $aMeasurement 606 $aMeasuring instruments 606 $aExotic Atoms 606 $aAtoms and molecules in external fields 606 $aClassical and Quantum Gravity 606 $aMeasurement Science and Instrumentation 615 0$aExotic atoms. 615 0$aAtoms. 615 0$aMolecules. 615 0$aGravitation. 615 0$aMeasurement. 615 0$aMeasuring instruments. 615 14$aExotic Atoms. 615 24$aAtoms and molecules in external fields. 615 24$aClassical and Quantum Gravity. 615 24$aMeasurement Science and Instrumentation. 676 $a539.723 700 $aPowell$b Adam Michael William$01886175 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911049102303321 996 $aMagnetic Field Characterisation for Gravitational Free Fall Measurements of Antihydrogen in the ALPHA-G Experiment$94521567 997 $aUNINA
